comment Can I use conduit to ground an antenna?
@ThreePhaseEel Not necessarily. The conduit may be feeding the meter pan, then the service panel could be fed by a cable or nonmetallic conduit.

comment 4 way switch controls two outlets and one overhead light oppositely
You should include some photos, and a better description of the wiring. As it stands, there's probably not enough detail for anybody to answer your question.

comment 4 way switch controls two outlets and one overhead light oppositely
If it all worked, why did you change it?

comment Can I use conduit to ground an antenna?
@ThreePhaseEel Sure, but like I said. If that conduit is used, it has to be bonded to the electrical system's grounding electrode (810.21 (j)).

comment Does the NEC limit the maximum size of junction boxes?
Yes, at some point it becomes a conduit.

comment Can I use conduit to ground an antenna?
You can only use the conduit as a grounding electrode, if you bond the conduit to the grounding electrode of the electrical system, or if it already is bonded. there's no shortcuts, if you want to do it right.

comment Can I use conduit to ground an antenna?
Sorry, I thought the conduit you were using was the conduit that the coaxial cable was running through (from shed to house). It sounds like you're going to have to drive a ground rod at the shed, and bond it back to the grounding electrode at the house. The diagrams in the answer I linked to will help you.

comment How do I ground a TV antenna on my shed with the cable running underground to my house?
The voltage potential in the earth varies from one place to the another, even over a short distance. Bonding the two locations keeps them at the same electrical potential. All the voltage in your home is in reference to ground potential (0). If "0" is different throughout the electrical system, you could run into problems. Bonding the two electrodes allows "0" to be the same everywhere.

@MarcRochkind Before you proceed, you should insure that the conduit is "electrically continuous". You can determine this by testing the continuity (or resistance), from one end of the conduit to the other.

comment Connecting three wire dimmer switch (black, black, green) to four-wire cable (red, white, black, ground)
Without any additional information, I'm just guessing. Green connects to ground. white is capped off. Red connects to one black. Black connects to the other black. However, there's no way for me to say for sure, since you don't provide nearly enough information in your question. Do you own a voltage tester, or better yet a multimeter?

This answer might be helpful.

comment Coast 3-way — does this conform with Code?
I'd guess that before x/4 cable, you'd use two x/2 cables. The grounded (neutral) would be grouped with the ungrounded (hot), and the travellers would be in the other cable. Or you could run four wires through conduit.

What exactly do you need help with? Are you looking for a complete tutorial on how to do this, or are you stuck somewhere while implementing your solution?

comment Does a plumbing vent need to penetrate the roof? (Can it penetrate a wall?)
This document lists the winter design temperature for some areas.

comment Does a plumbing vent need to penetrate the roof? (Can it penetrate a wall?)
I'm only speculating, but I would say because the vent is full of moist air. So you don't want the moisture condensing and freezing on the pipe wall, as this could lead to a blockage.

comment Buying used heat pump/AC
My concern is the refrigerant lines, and charging the system. Special tools and knowledge are required to charge the system, and it's very easy to mess up. Not to mention the fact that you may have trouble getting your hands on the refrigerant.

comment Sump pump & ejector pump: can I (and should I) change single dedicated non-GFCI receptacle to a dual receptacle GFCI?
@ThreePhaseEel Not according to the countless customer support, and appliance technicians I've talk to. They seem to believe that there are quite a few devices that are incompatible with GFCIs.

comment Is it worth it to repair a twelve year old refrigerator?
There's no way to answer this, without more information. Without knowing exactly what's wrong with it, there's no way to guess how much the repair might cost. Without knowing the model, it's not possible to find replacement parts.

comment Buying used heat pump/AC
Unfortunately, unless the equipment is actually installed, you're going to have to trust the seller. You'll also want to have a professional install the unit, unless you have all the tools and knowledge required to do so.

Don't get a system that uses R-22. They are limiting its manufacture, so it will be nearly impossible to get in the near future.
