Re: Would it be okay to put 2 Ceiling Fans on one circuit???

Oh... another real world example...

We recently replaced a swamp cooler at my church.

For those not living in arid places, a swamp cooler is Southwest air conditioning. A pump runs water over pads and a blower sucks air across the pads and cools it through evaporation. Works great in places where 12% humidity is a "sticky day".

We pulled the electrical box off the old cooler and I found 12 AWG thhn running UP TO the box, but a handyman along the way actually spliced in a piece of 18AWG extension cord from the box into the cooler.

This place also damned near killed me one day while replacing some lighting and I found out the hard way that there are neutrals being shared across circuits.

jvande7471, I would hate to tell you all the substitutes for blown fuses I have seen.

Since discovering (thankfully not the hard way) what a damn mess the previous owner made of DIY wiring in my house I will not touch a wire without checking it first with a non contact voltage detector.

The closest I came to problems was the discovery that a three gang box had two circuits passing through it and I had only switched off one of them. Not against code, I believe, but it sure made me much more careful to not just trust that the breaker had shut off power to the whole box...

Man! You guys are touchy! :D

Blame the amateur (me) for baiting the pros (just about anyone else who's posted).

I never touch any wiring without putting a meter to it. As you post you just never know.:D
It is not uncommon to have more than once source of power feeding into say a 3-gang box, mainly because 3 & 4-way switching & traveler requirements. Add to the mix box fill requirements as well. And that is completely legal, and rightly so, by NEC standards.

Even with the double pair of gloves, face shield, flash resistant clothing, and double insulated tools?:eek:

The gotcha I found with this was when working in a large room with multiple lighting circuits that shared return lines. When the breaker for one circuit was off, the lines looked dead. It was when I separated the return lines, saw sparks and watched the other lights go out that I knew I was in trouble. :eek: This was working overhead on 20 ft ceilings. One of those moments where you just don't move as you yell for people to turn the other light switches off. :)
