comment Can Romex (NM-B) be run through conduit?
Yes we've all heard this, but as far as I can tell it appears to be an urban legend. The conduit is already surrounded by several layers of rubber, a very good insulator of heat - the pipe it all runs through adds very little extra heat-insulation. But whether or not it's an urban legend, it's not supported by NEC code (see above answer).

comment Receptacle Tester Showing Open Hot
I'm really surprised we don't have a question asking what 'Open Hot' means already, given how basic of a question it is.

comment Is there such a thing as an actual 60W draw LED or CFL bulb?
A low-wattage laser can burn you because those the energy is focused into such a small area. I don't see how that's relevant to the wattage of LED/CFL bulbs at all.

comment Why would two circuit breakers be connected inside the service panel?
@Tester101 If that were the case, there'd be an open circuit between the two legs and both breakers would pop. I think his numbers must be wrong.

comment What are the differences between these two receptacles?
@abelenky The notch on the neutral (causing it to look like a sideways-T) is what differentiates a 20-amp outlet from a 15-amp outlet. The shape (round or rectangular) is purely cosmetic. But, it does make a difference, since you need to buy the correct outlet-cover to go with it.

comment How to turn off all power to the electric panel?
@Dannyboy: If you are not a trained electrician, you should never do work on anything electrical prior to the main breaker. Without that breaker, there is nothing to save your life if you make a mistake. Call an electrician.

comment Ceiling lights running dim
Based on OP's description I believe this is the correct answer.

comment Copper Water Pipes used as Electrical Ground
-1 It is common practice (and in my locality, required) to ground copper pipes. This increases safety (if a hot wire touches a pipe, you want a breaker to blow, not every pipe in the house to become charged). Also, since the pipes have a separate path to the earth outside, it helps prevent stray current-loops. An outlet tester cannot tell you if your pipes are grounded, unless OP's pipes were the only path to ground.

comment My appliances are shocking me…but only me
This sounds like normal static shock. Do you live in a dry area? Wear wool shirts/socks? Walk around the house in rubber-soled shoes? When you touch these things for a few seconds without letting go, do you feel only a single shock (static shock), multiple distinct shocks at regular intervals (electric fencing), or a painful numbness that travels quickly up your arm (leakage from a 120V line)?

comment How can I repair a ceiling fan that hums, but doesn't turn?
+1 I am coincidentally having the same issue, with a living-room ceiling fan that is only a few months old. The humming is definitely not the lights - the hum stops when we turn the fan off, with the lights on. Related: diy.stackexchange.com/questions/46276

comment How can I protect a vending machine wire from being cut again?
Bolt the machine down? Tape the wire so it's not hanging on the floor?

comment When wiring a mains plug, why are the cables squeezed under the screws and not circled around?
"Screwing the conductor into the terminal in the plug gives a much more secure and resilient connection." - This is the opposite opinion of everything I've read on this site. Also it makes no sense - how could wrapping around the screw and squeezing the wire with the screw be more secure/resilient than only squeezing?

comment How do I remove stuck (melted?) foam from under carpet on hardwood floor?
We ended up trying literally dozens of different products. The one that worked best was (surprising us all) Orange Goo hand cleaner. There was some concern about wiping away the finish, so we waxed it immediately afterwards. I think the concerns about the finish were unfounded though, almost a year later and the floor is still looking great!

comment Is there any code for running Ethernet cable (through attics)?
Thanks! Another quick question: I see supports like these all the time. I assume these fall under "cable ties, hangers, or similar fittings". I notice in the picture that they go along the upper-edge of the basement wall. Is this an acceptable workaround to avoid having to drill through the joists?

You can also do it without draining the entire water heater

comment How can I identify the conductors in an appliance cord with only the green wire colored?
Small correction: hot actually alternates from +170V to -170V. 120V is the RMS average.
