Measure the outer diameter of the cable. Use Pi R squared to compute the area. If it is larger than .269 sq inches you cannot run 8-3wGn cable in 3/4 PVC 40 conduit. This is based on 53% fill. If...

Do you mean that you tested a wire with a hot stick, it indicated dead, then when you pulled it out of the box it sparked? When working on an old house, I recommend shutting off all circuits except...

If installed on the top of the counter, you would need a periscope or pill box type of enclosure or a vertical wall or split level counter top wall, so that fluids could not be easily spilled into...

The list of codes being followed is just a starting point. What matters is the local authority having jurisdiction (AHJ) interpretation of the codes. For example, one city near me says no AFCI...

It is OK to run cat5 or phone wires in metal conduit as long as you ground all the conduit. If you run any shielded (foil wrapped) communication wire, you must ground the shield or it will create its...

The problem with using #12 on lighting circuits is that you will probably cram too many wires in a box which is a Code violation. Some AHJs require all receptacles to be on 20 amp circuits.

If your inspector allows you to use grommets they must be stapled within 8 inches of the box. Some allow lots of cables going thru one big grommet. Others say one cable--one hole.

In my area, the electrician gets a permit and calls for inspection. The next morning PGE disconnects the power. After inspection, PGE reconnects the power the same day. I have the homeowner ask a...

Can I install a DW air gap outside the house? I have a one piece molded countertop/ sink. I could do it on the counter top but it would not drain into the sink it would drain onto the counter.

I have hard, rusty, water from a 140' deep well. Also every year or so, I start getting rotten egg smell, so I sterilize the well and pipes with bleach. I am using a simple filter, but the kids drink...

I had the same rust and particle problems including manganese(black elongated particles). I replaced all well pipe with PVC but casing is steel. The plastic did not solve problem, but I like how it...

two 2x12s w/ plywood are not rated to be as strong as one 4x12.

No need to remove the 12-3 just add a 12-2 from lite box to lite box.
Note to JWelectric: I said to simplify conversation, we call the wires hot-neutral-ground. I think electricians talk this way....

In simple 120 volt residential wiring, the white wire is called the grounded conductor. In 240 volt residential wiring, the white wire is called the neutral conductor. Technically speaking, in a...

I do not see any problem with placing a portable hot tub over a conduit buried over 18 " underground. That is why you bury it.

Assuming that it is a Kohler problem, I'm sure they are working on fixing the electric current leak in their control panels. But it will be a wait for the replacement part. In any case, the switch...

You will not lower your wattage used with 3 phase. It takes a certain amount of power to pump air or water or run lights and as long as the motors, etc. are in equally good condition they could be...

If you install a switch between the GFCI and the tub it will solve the tripping problem. And indicate a Kohler control panel problem.

Coat both sides with pipe dope. Tighten the fitting. then take it apart. You will see that virtually ZERO pipe dope is on the threads. That is why I use teflon tape.

Oil is toxic, caster oil will rot over time. Use plumber's lube, the stuff you put on shower valves to make them work smoothly. It is non-toxic for many years.

How about a piece of 3 inch ABS with notches and a T handle? Easier to cut than steel. Also to cut down on flex in the plastic pans, I set them onto 4 piles of cement mortar on tar paper.

Run a 12-2wG from one light to the next light. The second light has no neutral. Do NOT try to use the bare ground as a conductor!!

The problem is in the control panel for the tub. Install a 240 v. switch downstream from the GFCI and upstream from the control panel. I think this will eliminate the tripping and prove that it is...

This was seen on a house inspection for a friend. I recommended that an earthquake strap be installed, T and P drain line be run to the soil and that a licensed plumber inspect the WH flue.

Have a propane WH mounted under the house in garage. For the flue, is there a rule as to how many feet horizontal you can go before you go vertical up to the roof? In the horizontal run, do you make...
