comment Why do I have voltage on a plumbing ground strap, and is it dangerous?
@Bryce: I'm struggling to envision a shared neutral wire that you could break off in a closet. It seems much more likely that it was a bonding clamp.

comment Why do my led bulbs state: not for use in totally enclosed luminaries?
-1, "I did it and it didn't hurt me" is not an acceptable answer. The majority of dangerous practices will not harm the majority of people, but that still doesn't mean it's okay to go smoking at the gas pump. This answer needs to state what the actual dangers are so OP can decide if the risk is acceptable.

comment Can I connect copper wire to aluminum wire?
@Tester101: Relating to old aluminum wiring: nachi.org/aluminum-wiring.htm According to the Consumer Product Safety Commission (CPSC), "Homes wired with aluminum wire manufactured before 1972 ['old technology' aluminum wire] are 55 times more likely to have one or more connections reach "Fire Hazard Conditions" than is a home wired with copper."

comment Can I connect copper wire to aluminum wire?
Don't just splice the two wires together, you need a special connection. When two dissimilar metals touch, a process called galvanic corrosion occurs, causing one of the metals to rust much faster than the other (this is actually used to a positive effect to prevent corrosion in water heaters with a so-called sacrificial anode). Also, the wires will expand/contrast due to heat differently, which will loosen the connection.

@JonH: Keep in mind it's an apartment building, we don't know how large it is.

comment Is the Electrician trying to scam me?
@statueuphemism: Your interpretation doesn't really make sense with the rest of what's written. I read it as, the circuit the outlet is on is currently drawing 36-49 amps. You can measure this easily using a clamp meter. And he's correct that this is extremely dangerous. However my first question (which he did not answer) would be, why is the breaker not tripping?

comment Is it safe to install a three pronged wire into a four pronged dryer?
Tim you are incorrect, it is not NEC-compliant to have a bare THHN wire coming out of the outlet like in your left-drawing. It is of course electrically-equivalent, but it looks extremely unprofessional (which is a large part of the NEC - it's not only about safety). If you already have a dedicated ground coming to the outlet (which is the hard part), you should just replace the dryer-cable and outlet with a 4-pronged connection (the easy part).

comment Can Romex (NM-B) be run through conduit?
As mentioned in the accepted answer, this is an incorrect myth amongst electricians. The answer quotes the NEC, which explicitly states "Nonmetallic-Sheathed Cable: Types NM ...", which is not referring to THHN.

While interesting, what does this have to do with home improvement?

comment How do I remove stuck (melted?) foam from under carpet on hardwood floor?
We also did all that, and also had the nasty black stains. We eventually found a much easier solution than sanding/staining - I'm sorry I never posted it before today. Please see my answer below.

comment Just bought first impact driver, do I still need to pre-drill holes?
What if it's not prone to splitting, like a 2x4? (or are 2x4's prone to splitting as well?)

comment Why are GFCI systems typically in the receptacle instead of in the breaker?
"but is beyond the skills of most amateurs" - I disagree with this statement. Installing a GFCI breaker does not take much more "skill" than installing a GFCI outlet.

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.
