It may be useful to note that the rules for the wires the utility company can use (for between the transformer on the pole and the top of your mast) are different than the rules for what size and...

I'm interested in what the experts think about the distance. How far can you run #12 before it can no longer be used with a 20-amp breaker? I think he said his run was about 125 feet.

Also, it...

I had a similar situation with dimming lights and clicking backup power supplies on the computers. Mostly it happened when other appliances came on, but sometimes when nothing else seemed to be...

For what it's worth, when I put my hot tub in, the local inspectors told me that because it was a self-contained unit (considered "portable"), the bonding did not apply. Of course, the equipment...

I smell a typo. It looks like it may have confused the OP. Pretty sure Ray meant "240 volt breaker". The amp rating would be 20 amps for each side.

Tracking down a defective neutral

When certain loads are on (microwave, gas furnace blower), certain lights in my house brighten noticeably. I believe this indicates that we have a fault in the neutral wiring somewhere, most likely...

One factor is the cost of the 20-amp receptacles that will be required. A quick check of Lowe's web site suggests that 10-packs of plain white receptacles are about 25% more for 20-amp versus...

Unless "outlet" is somehow defined to include hardwired light fixtures and switches, I don't see how it could be said to cover *all* lighting runs. ???

Ah, then I was incomplete. My thought was that if you have the control box, you could (a) hook it up, make the motor run, and take some measurements and (b) look inside the control box and see what...

I think you should connect it. In general, if there is a ground connection, connect it!

If you don't connect it, you would need to label that outlet "no equipment ground", IIRC.

Yes. Clearly those code writer never lost a fridge full of food ($$$) because of a false trip on a GFCI. If a fridge in a kitchen doesn't need to be GFCI, why should one in the garage? And I'm...

I'm no pro, but I thought I'd seen 220V GFI breakers that did not require a neutral. If I understand correctly, the only reason neutral is needed for the GFI breakers is to give a place for the...

One possibility (and I'm just speculating) is that "14 AWG" is a *minimum* size, and a manufacturer in the past may have found that making it a little oversize made up for looser manufacturing...

Per the owner's manual (http://www.jacuzzihottubs.com/request-brochure/brochures/2007_J400_LCD.pdf) the tub has a 36A max current draw with a 50A breaker and 23A max with 30A breaker.

Is your concern amperage or breaker count? My tub has an option to use a 30-amp breaker. Set up that way, the heater won't run at the same time as the hydrotherapy pumps, but our climate is mild...

Going under sidewalk

I priced 6# wire for my hot tub and it will be over $300 :eek: for the wire alone for the 120' route I had planned. Well, there is a subpanel in a nearby building (garage/shop) fed by a 50-amp...

Can I add 50 amps to my subpanel?

One more hopefully quick question before I head off to permit land. I'm planning to add a 50-amp breaker for a hot tub, but I'm worried they may not allow it in my subpanel.

Here's what I've got:...

Wow, I thought intentionally building strain into the run was a big no-no, but maybe I'm confusing it with water pipes.

220V GFCI breaker

As you are probably aware already :) I am putting a hottub in my back yard. Most of the "cutoff" boxes seem to come with GFCI built in, so the simple thing would seem to be to use a regular breaker...
