Electric Free Campin

Hi, I want to power a table fan (50 watts) using a battery. In India the input power to appliances (fan in this case) is 220 volts / 50 Hz. so can i power the fan with TWO 6 volts 4.5 AH sealed lead acid battery??

Can u please tell me how to do the power calculations? i want my fan to run for abt 4 hours. how many batteries do i need?



(im planing to charge the battery using solar panel but thats another question)
      

I am considering adding solar panels to my home to generate electricity.  I will not add batteries however (to expensive) so when the grid goes down I won't get energy from the panels (you need a special inverter and batteries) so I want to add a portable gas generator for those, hopefully, limited cases.



I just wondered how the solar wiring gets interfaced into my system (breaker panel?) and can I later add a transfer switch or interlock switch when I add the generator?



Or should I do that at the same time (perhaps the interface is complicated)?



Thoughts?



Thx
      

I have a 120vdc treadmill motor that has a motor controller board and a transformer to operate it. My question is is there any way to rigg it up to a 12v deep cycle battery. I was thinking all i would need is some sort of step up transformer 9-1 if they make it or 10-1. I would aslo like to have speed control which i assume would work through lowering the voltage. It runs fine off the 12v batter just not near the rpms i need. I know it will drain the deep cycle very fast but im not worried about that.
      

My brother-in-law has a Coleman 8750 Watt portable generator with a 13hp Honda engine.  Worked fine for a couple of years and then all of a sudden it wouldn't provide any voltage at the outlets.  So he called up Coleman and they said the problem was probably a $50 control board.  So he ordered one and installed it.  This temporarily fixed the genset but after an hour or so the electric quit again.  So it appears something is causing the control boards to go bad.  Any idea what could be causing this?
      

Am doing a bathroom reno and installed a new fan. Original switch was a simple on off single pole. I want to install a DewPoint condensation fan switch that will turn on automatically at a certain moisture level.

The new switch as 4 wires. green ground, red fan, black power, and white neutral. I know the ground, but how do I hook up the neutral and fan to the existing fan set up?

There is a double pole light switch in the same box that has a couple wires to it, and there is a mass of whites that I am not sure where they go



Can I hook up the neutral somewhere else, or put it with the fan like a single pole? What do I do with this?



In the attached picture the switch on the right is the 2 pole light switch and on the left is the fan switch that I hope to replace.



Your Advice is appreciated
      

Hello everyone,I have a question about a forklift battery charger i bought. Ok,its an exide forklift battery charger 36 volts. It weighs a ton so i am having to run a 25 foot extension cord to it. My question is,my 220 wall outlet has three holes so i went to lowes and made a 220 extension cord. Now i get to the ac cable coming out of the charger that hooks to the extension cord(plug was cut off),there are 4 wires coming out of the cable green,white,red, and black......the guy at lowes said i could buy a 3 prong plug for it to plug into the female end of the extension cord because one of the 4 wires is probably neutral and i wouldnt have to hook up but the green,white and either the red or black.....is he right? Inside the charger the red,white and black all go to big fuses and green to ground. Also above the fuses it says "factory set to 480 volts ac". I guess my question is,will this charger only work using a 4 prong wall outlet(mine only has 3) and with 4 prong plug hooked to cable coming out of the charger itself or is the guy at lowes right in saying that only the red OR black wire has to be used? Sorry if this is confusing but ive searched and searched online for 3 days and havent found anything. Thanks in advance for any help-Kevin
      

Hey guys, I am looking to find out what kind of cable this is.







Some details



It looks to me like some kind of. 



3 Conductor surface shielded Cable



The outside is a black shield



It has 3 wires: red, gold green that were twisted together and have some kind of coating on them, not rubber but a color coating on them.



Its a verrrrrrry thin cable and the wires are individually twisted with about 8 strands and then the 3 twisted and then the outside.



Anyone have by any chance of this laying around or know what this kind is?
      

I have a pendant light over my kitchen sink, it's been in place for about 8 months. It seems to burn out bulbs a little quick, and they're usually a white smokey look when they do burn out.  Also, the cable next to the light is turning from a clear to a brown. I'm not sure if it's just from heat, and is ok... or if it's a hazard?  I don't see any evidence of melting on the cable or in the light socket.



I checked voltage, and it's around 121.5.  The fixture uses 60 watt max candalabra bulbs, and that's what I use in it.
      

I'm using very bright incandescent lights through chickens lamps to increase my metabolism. The reds and yellows that come out of incandescent bulbs do this. My question is how can I increase the production of reds and yellows? Is there anyway I could change the wiring in the chicken lamp to force it to produce more reds? I heard that putting a 130 volt bulb in a 120 watt socket will produce more reds? Any other ideas of mods I could do to the lamp? I was also wondering if red heat lamps produce more reds and yellows then regular incandescent light bulbs or do red heat light bulbs just have red coated paint which makes them appear like their producing more red?
      

Hi.  This is not exactly home-improvement-related, but I'm hoping some of the electrical gurus out there can answer my question.  I am building an underwater fishing light.  It will basically be a sealed green acrylic tube with LED bulbs in it, powered by a 12V DC battery.  It will be submerged between 2-5 feet.  I imagine it will be used approximately between 2-6 hours at a time, so the cable will not be submerged in water or a wet area permanently. 



Obviously I am doing this to save $$ (they are expensive otherwise), and I find myself wondering why I can't buy an inexpensive extension cord (lamp-cord-style) and use it for the power from battery to light.  I started looking at garden lighting wire, but that stuff is very expensive.



Would auto electrical wire (with shrink tubing) be sufficient (though I'm not sure I can find shrink tubing with enough length)?  Speaker wire?  LOL. 



Any suggestions would be appreciated!



Edit: One thing I forgot to mention is that I don't want the power cord to be heavy at all.  Nice and light is the key!
