Federal Pacific Breakers...fire Hazards

Hi, I'm wondering about the following. I have a hood fan at a fast food restaurant and for a while now there's been a situation where some days I go to turn it on in the morning and it goes out a few times. Some days it happens, while some days I flip the switch on and it runs normally. When it goes out I have to go to the circuit breaker box to trouble shoot it in order to get it going again. Is an issue like this a fire hazard or is the trouble shooting saving it from a fire while still indicating there's something going on?
      

Greetings,



I am looking to wire a sub-panel in my barn to support a general workshop.  Loads would include standard woodworking tools (including 220V table saw), welding, air compressor, etc.



The house has 200AMP main breaker and minimal in-house loads.  Dryer is gas, Oven and cooktop are gas.  Water heater is off the oil furnace.  I think the biggest single load is the well-pump and/or fridge compressor.  We do have sporadic toaster oven, hairdryers etc.  Otherwise its just lights, ceiling fans, flat-panel tv, stereo...



We had 4" conduit installed to the barn, so there is plenty of room to pull a big cable.  The entire run from the house panel to the barn totals around 155' (probably less, but rounding up)



My questions a



Can I pull a 100AMP sub-panel from my main house panel as described?


Would 4/0,4/0,4/0,2/0 aluminum service entrance cable be a good choice for this run?  Could I do it with something lighter?


Could I put an additional sub-panel in the garage (about halfway to the barn) by interrupting the run?  The garage subpanel would have a 220V plug for possible welding and/or electric car charging.  Would this require a separate run?


Are there any other considerations I should be thinking about in planning this?




Thanks for any thoughts you can share on this! 



Cheers,



pete
      

hi everyone.



i am installing 4" recessed lighting throughout my main floor.  my house was built in the 40's and the previous owner installed drywall over the existing lath and plaster ceiling.  so I've cut a trench down the center of my room to drill floor joists to run wiring and cut my holes for the new lights.

the lights are fire rated and do not require insulated cans for a traditional installation in a drywall ceiling.



question i have is with the additional 1/2 to 3/4" of lath and plaster above the drywall, should these lights now have insulated cans or should i be fine with the cans I've got?  there is no insulation in ceiling.



any suggested would be appreciated.



thanks

I am redoing my basement, and i am making the electrical runs for the recessed lights in the ceiling. I am using 14 gauge wire, and i have 16 recessed lights with 65 watt bulbs in them, however they are rated at 75 watts max. assuming someone after us may put in the max bulb, the total watts would be 1200, equaling 10 amps. When all of the new wiring is done, i am going to have an electrician connect the circuits to the circuit breaker (using 15 amp breakers) however since i am not comfortable doing this myself, and i would like to use the lights now, can i connect them to the existing 12 gauge wire (this will not overload the breaker... i already checked what else was plugged in to the electrical outlets).



to recap:

The power draw will only be 10 amps at MAX. capacity

existing wiring is 12 gauge/ 20 amp breaker

electrician WILL connect 14 gauge wire to breaker using 15 amp breaker



*THIS WILL BE TEMPORARY*
      

I was in my attic today doing some work when I noticed a bare twisted copper wire that ran along a ceiling joist.  All along it was charred wood and charred  fiberglass insulation.  Luckily the fire it caused did not sustain itself and I was able to find the problem.  I then traced the wire and figured it originated in my breaker box (although I could not determine exactly where in the box).  It then ran across my attic alongside a ceiling joist and down into a wall ending up connecting to my water meter.

  Several months ago,  the electric company was restoring power to my area and ended up sending a power surge into my house taking out an oscillating fan, a toaster and a GFI outlet.  Last winter, I also had to have my electric meter pole replaced by an electrician after a tree branch took it out during an ice storm.

  I was wondering if one of these events could have caused the ground wire to heat up or something else entirely is going on?  I am suppose to have a company blow in  insulation soon and I need to figure this problem out.  Any help would be appreciated.  Thanks.
      

We recently purchased an apartment complex built in 1950. Inspector's report advised us to upgrade the main electrical panel (fuse box) on the  outside of the building. He also advised us to relocate fuse boxes in closets stating it is unsafe and a fire hazard.

We met with several electricians to get a quote. It's so confusing because everybody says different things... 



FUSE BOXES IN THE CLOSET: One electrician advised us to flip the panel into the bathroom(closet is adjacent to bathroom) and install a breaker instead of a fuse box, another electrician claimed it's not up to code to have breakers in the bathroom.



MAIN PANEL OUTSIDE THE BUILDING: One electrician advised us to upgrade the amperage (currently 30 amps), the other claimed it's an unnecessary change that drives the cost up since we do not have any appliances that require high amperage: no washers or dryers.

So confusing. I want the property to be SAFE for our tenants, but cost-efficient for us. Any thoughts?

thank you.
      

In my older home i just founf out that all the upstairs ( 2 bedrooms) outlets are installed on the same 20 amp circuit breaker for my kitchen. which might be a reason that when too many things are running this breaker trips. My question is I want to add a 15 amp breaker and isolate all the upstairs on this breaker so the kitchen stays seperate. i Found the romex that is installed to a downstairs outlet that is connected to all the other outlets upstairs but since it is hidden in the walls and i narrowed it down to 3 possiblities upstairs, but i am not sure. How can i test to see which one of the romex wires it could be so i can attach my new romex from the new breaker and just abandon the old wire all together.

PS. when i disconnnect the romex from the outlet downstairs in the kitchen all the outlets upstairs stop working, that is how i know that is the one that brings the electriity upstairs.
      

I'm new to the forum and I don't mess with electrical issues.  I leave it to the pros.  My question, I'm looking at buying an older home.  It is upgraded to a 200 amp panel, has 3 prong outlets, but the owner said he never ran a gound from the box.  What are the pitfalls / safety hazards of not having grounded outlets?  thanks,
      

I have read and searched a bunch on wire size and I wondered if you guys could confirm that #2/0 copper is fine to run from the meter base to the panel.  Upgrading to 200 amp service, 200 amp base and 200 amp panel.  From what I gather its ok for service wires at 200 amps, but in other applications its rated for less.  For what its worth, the poco is running #4/0 to the the meter for the new service.
      

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!
