Upgrade Svc., Overhead; Bill Vs. Estimate Question
Appreciate any help with this.
Background: - new to us old house, got three quotes for an upgrade to 200A service plus addition of three new circuits in conduit with receptacles (Chicago area, conduit is code in just about every town around, I have no issue with that); - existing service to house was overhead, opted to keep it overhead and not bury it; - the quote says, exactly: "Installation of a 200 amp 240 volt overhead electric service complete with riser, outdoor meter socket with a 200 amp disconnect, 40 position circuit breaker type distribution panel..." etc.; I understood from discussing the work with the contractor we chose that install overhead service meant to include the work and materials needed to upgrade the line coming from the pole at the alley to the house to handle 200A capacity; paid 50% down on quote; - the morning the boss and tech show up for the work, boss says we already have a 200A overhead, which I seem to recall the home inspector mentioning months ago before the closing (makes sense because the overhead runs to a single room addition put on several years ago), but boss was the guy who came to the house to quote the job in the first place, didn't mention anything about the existing overhead capacity at the time; - the work gets done, seems fine; tech left without going over anything with us but whatever. Final bill matches the quote to the dollar. There is no indication that there were any surprises during the work. Since the quote says installation of overhead service and they didn't need to replace the overhead lines from the pole I think the final bill should be lower than the quote. The distance from the pole to the riser is about 40 feet. Should I expect from the wording in the quote that the final bill should be lower than the quote because they didn't have to touch the existing overhead? About how much lower? We didn't go with the lowest quote, didn't beat him up on price and the total bill is quite a pretty penny, so I think he would be making good money either way. I know there is no way for someone to tell me an exact dollar figure here based on a blog post, but I'd like to get some kind of idea so I can start my conversation about the final bill. Thanks for any help out there. Similar Tutorials

I'm having quite the time finding an electrician who will quote this. Just about all of them say that what I need is to upgrade my main panel but I want to install a new main panel that is a part of the meter base outside and make my current 100A panel a sub. Maybe you people can tell me why nobody seems to want to do this. Here are a few shots of the existing meter (note what is apparently a 60A base here)
and a shot of the conduit headed underground. Like most homes built during this era, the conduit makes a right turn underground to enter through the cinderblock, ending up coming into the back of the main panel. This conduit encloses a 4 wire feed. edit: no, actually it is only a 3 wire feed which is a problem if I want to convert the original main panel a sub. Here's the existing panel. It's a 60's era Square-D split panel with a 30 amp sub panel for the finished basement. Those are low voltage wires to circuit taps for my home energy monitoring system btw. The reason I don't want to upgrade this panel are as follows: We won't be expanding the electrical west of this panel any more. All planned expansion (240v car charger in Garage, planned 3 season room with grid tie Solar on the roof) will be to the east. Upgrading the panel will require major surgery to the walls. Due to the way the original basement is engineered there, the walls have an intricate stud pattern behind the existing panel. I'd pretty much have to rip out a 4' section and redo it to make the access large enough to handle a 200A panel. Adding additional circuits to an upgraded panel will require an act of God due to the finished basement construction. There are no raceways for additional circuits. Based on this, my thoughts were to create a new 200A main panel outside based on something like the GE model TSM420CSCUP loadcenter. Here's a shot of this panel: This particular panel has room for three 2-pole breakers in addition to the 200A mains. I'd add a 100A 2-pole breaker for the existing panel, with the other two reserved for the garage/solar expansions. The issue with the contractors who have quoted the job appears to be the conduit going to the existing panel. I'm not sure what's wrong with it but it is apparently not compliant with current code. Obviously the bonding needs to change, new grounding electrodes need to be driven, and a water pipe ground needs to be established to the new main panel, but what else is required? I'd like to throughly research all the code considerations here so I can approach a contractor from a more knowledgable perspective then determine the best way to perform this upgrade. Due to POCO coordination and the need to cut household power for the duration of the job, I have no desire to DIY this one... So what exactly is wrong with the conduit running from the existing meter base to the existing load center? Why is everybody telling me that I can't do essentially what I've described above? What are the relevant code sections that will apply to this job? Should I be chatting with my AHJ about local considerations now or should I wait until I have the code requirements down pat (assuming the latter here)?
Now I have a 20 amp breaker at the circuit box that has older two wire, ie black and white no ground. This cable looks to be in good shape. This services several overhead lights in bedrooms. I need to tie into this to create overhead lights in the bathroom and hallway. Can I replace the 20 amp breaker with a 15 amp breaker, and then use 14-2 cable to connect the bathroom and hall lighting? I do not know if the present older cable is 12 or 14. I assume it is 12 since it has been tied into this 20 amp breaker before I bought the house.
Thank you to all who help.
Hello All,
First post, working on a complete bare-stud remodel of my home, so I will try to be descriptive enough. I have a 150 Amp service to the house (which I might upgrade later) with a meter socket and breakers outside. I am running into the house (more than 10') to a 125 Amp 20 space ML. I have too many 15 and 20 Amp circuits now for the panel and need to change it out. The house is rather sprawling, so the rather than tie rooms together in a confusing way, I broke the circuits down per minimum requirements... almost none of them are near capacity. I am going to run the big stuff back out to the exterior panel/service however I still need more space in my interior panel. What I REALLY need is just a 40 circuit 125 Amp GE panel but I don't think those exist because (guessing) *most* 40 circuit scenarios need more amps. What I wanted to do was upgrade to a 40 space panel (only been able to find a 200-Amp). I realize I am still limited outside by the service and have already run 4/0 aluminum. I know I am not going to go anywhere near the 200 Amp capacity, I just need the space. Is this ok? Any reason I shouldn't use a 200 Amp MB panel? Thanks!
I'm trying to fix a problem with a track light installment over the a bar I've just put in. I've done it before. never had issues. but this particular problem is driving me nuts. It just defies logic. The electrician who actually installed the associated dimmer switches with this dining room area was called as it seems it may be a flaw with his wiring, but he's blown us off and I have to try and solve this myself.
This is how it's all set up. I've been rehabbing our home from top to bottom, and converted our old kitchen into a dining area. Within this dining area are four sets of lights, all controlled from one box containing four dimmer switches. I set up all the new wiring and installation of the lights in the ceiling, and we paid an electrician to come in, check everything out, set up the multiple switches, and connect it all to the board. It's all new copper wiring from beginning to end, as I didn't want to connect or splice in to the old aluminum wiring that was in place. All the new wiring and lights are on a dedicated 15 amp breaker. Three of the sets of lights were set up to be available from the day the electrician came around. The fourth, for the track light over the bar, was left hanging from the ceiling capped off and with the switch off, as I still had work to do installing an overhead wine rack, under which the track was going to be set. Two days ago I finally got around to putting the track up, but after setting it in place and connecting the power up the lights wouldn't work. I took the lights out to our kitchen, where I installed another track light system some time ago, plugged one of the lights in, and it worked just fine. I then went back to the bar area and used a spare track, then a spare connector, to see if I could isolate the fault, yet neither of the items provided a solution. Now here's the weird bit - every time I tried checking the system out, I'd get 120 volts showing from the wiring and from the track when I'd test with the multimeter. But the second I'd put a light into the track, the multimeter would drop to zero on the voltage reading on either the wiring or the track. Take the light fixture back out, and the voltage would pop back up. Inserting the light was thus completing some kind of odd loop. It wasn't just one light - I double checked by grabbing working lights from the kitchen track and inserting them into the other track - the same problem would pop up. Finally, having come to the conclusion that there was nothing wrong with the track at all, I took the whole assembly over to a nearby wall outlet, used some spare electric cable to connect up to the appropriate slots - presto, the light came on! I even double checked all this by grabbing another light fixture destined for our bathroom, and tried connecting it to the wiring over the bar. Nothing. Yet as with the track light, the minute I took it over to the wall outlet and connected it, the light worked. So everything logically points to the fact it has to be something to do with this individual circuit, right, because a) the light fixtures work when plugged into another circuit and b) the other three dimmers and lights hooked up in the same box work fine and draw power from the same wire cable/breaker combination. The only things left that I can think of is that the electrician has either wired the dimmer switch up incorrectly or that there's some kind of flaw inside the switch itself. Does this make sense? A friend also told me to double-check to make sure that the black wire feeding power to the light was indeed the hot wire, and it is. If I touch it with the black test lead from the multimeter and put the red one to the neutral I show 120 volts. If I keep the black test lead on the black wire and put the red test lead to the ground - I also show 120 volts. A final point. I know I'm not overloading the circuit - not even close. With all four dimmers maxed and every light on - including the test light on the track - I'd only be drawing 8 amps on a 15 amp breaker, besides which I'm only using one set of lights while I'm working on this problem anyway. This is a dedicated circuit, so there's no additional power being drawn away by something else. So how am I getting 120 volts from this wiring, according to my multimeter, yet it won't light up ANYTHING and keeps giving off the indication that some kind of loop or short is being created every time I actually plug a light into the track? It's got me totally stumped. Anyone have any ideas?
Hello all. I'm new on the forums and new to electricial. I bought a house recently and found some outdoor outlets that don't work. Only one does. I've searched the forums and found some troubleshooting steps such as reset all the GFI outlets in house, but that didn't resolve the issue. None of the outdoor outlets are GFI (they don't have a button). I only have one circuit breaker and I've looked around and didn't find a second one. None of the circuit breakers are label for the outdoor outlets and they are all in the "on" position. All the indoor outlets work fine. What other troubleshooting steps can I do before forking out $$ for an electrician? Thanks!
Scratching my head on this. New pole building. For now, I want to use one circuit for the lights. What I'm trying to do, is, at one door, I have a 3 way, switching two flourescent lights. Also in that 4-gang light switch, is run a light over the door on the outside, and a light over the overhead service door, and another light over the door, on the inside. So 1 3way, and three single pole switches. At the back door, the other 3 way for the same two lights, and a light over the door on the outside, and another light over the door on the inside. I have the power from the m/p, going into the light box nearest the M/P. Long story short, instead of how I have it, which operates all the lights, as long as one of the three ways are on. If someone could help me with how it should be. I am using 12-3 from the switches. Using 12-2 from the first light box, to the second. I have a another 12-2 running into each switch box, to supply power for the single pole switches.
Thanks for any/all input.
Hello everyone,
I am trying to replace a 40-year old garage door opener that stopped working, and the motor reads "250v"-- are 250 volt openers standard? does the 250v mean something completely different? or will I have to re-wire it to a standard 110v outlet type to put in a new opener? The original cover has most likely been lost to time; the brand was Overhead Door company. I haven't purchased any new openers yet, making sure I know what I am getting into first :-) The door is not especially large --9'x7' not sure of their weight; if it matters, the door will likely be replaced shortly as well. Thanks for any and all help!
I have a grounding question. I am installing 400a service to my new home. We ran 350MCM wire underground thru 3" conduit from the 2ndary terminal (moped) to the house into a 320A Cooper B-Line meter. From the meter we ran 2 sets of 4/0-4/0-2/0 thru the wall to 2-200a breaker panels ("standard practice", according to my electrical supplier). The ground wire (#4Cu bare) from the grounding rods comes up from the ground and we're curious if there has to be a special splice connecting the ground wire to each breaker panel or can we run thru one breaker panel to then next, say by connecting the ground wire to a ground bus on one panel and running that thru to the next with #4Cu bare or #6Cu in conductor. Different electricians are suggesting different methods and the electrical inspector is unsure, but seems to be leaning towards the "special splice". Any feedback would be appreciated.
Hi all
I'm renovating a rental home I bought. It has the original 90 year old fuse panel and I'd like to replace it with a modern panelboard. Here's a picture of the current setup: I'd like to demo the inset fuse box cabinet and then mount a new panel on the wall to the left. The service conduit goes inside the stucco into the building. I'd like to cut it, put in junction box, and a sweep and extend the service to the left to the new panel I called our electric co. to get the power disconnected and strangely the rep told me "Oh, people usually just work on it hot". Is this true/feasible?? Your advice is appreciated
I am installing central air conditioner in our 80 year old house. Debating between one high velocity system or two conventional systems.
We have 100 amp service with an electric dryer, stove and oven. Water and heat is gas. The HVAC contractor told me that he spoke with the electrician who assured him that we would not need to upgrade service but add in a sub-panel. Any thoughts? What are the risks of staying with current electrical service and adding A/C? What are the risks of upgrading to 200 amp with such old wiring? Is one high velocity system better than two conventional systems? Note I am cross posting based on another question I had in the HVAC forum. Thank you in advance for all your help. |
