No it doesn't. The NEC only requires it to be at least 1/4" into the panel not any less... you can run it 8 inches into the panel if you want. Keeping the sheaths of the cables stipped back generally makes for a neater look and better wire management but that is all.Doesn't the sheathing of that 12/2 cable entering the box need to be cut back?
Not because of the 08 code. But because we have enough circulating neutral currents as it is, we don't need any more. When we drive a ground rod and tie it to a neutral in a 3-wire feeder, we create a parallel path for neutral current. Sure, the impedance of the earth makes the amount of neutral current in the ground small, but still nonzero. This small current is finding it's way into everything it can to complete the circuit. Some of it is going back on the phone ground, some on he cable tv ground, some on the neighbors ground, and so forth.If he uses 3 wires and has no other metallic paths, explain to me what exactly would make it not a good installation. Electrical theory please, not an answer of "well, if it was so good why is it not allowed in the 2008 code".
If the panel can accept the half size breakers they are OK. The only problem that I see with them would be heating due to crowding.Is there a major difference in the half pole breaker apposed to the full pole if they are the same amps.
Does it make a difference for ground rod copper or aluminum .the electrical place sold me the aluminum and said its only ground its not a major problem using this rod.
Find the panel part number and see if it can be converted to a main breaker panel. I personally don't know if it can right off hand. But often the lugs can be removed and a main bolted in place. Barring that, you can either replace the panel, or buy a disconnect switch and mount it near the panel, or back-to-back with it.I was told on one of my threads to add a main shut off in this panel how do i do that because at lowes they have no idea.
And besides code is there another reason bare wire need to be 24" deep
Okay, I must have read it wrong then, I thought it said it could ONLY BE A CERTAIN LENGTH, not that it was a MINIMUM length. Thanks.Andy
NM-b cable sheathing must extend into the box/enclosure at least 1/4" not 1/4" or 1/2" and less. You can run it into the box 10 inches if you want.
.Whatever size your feed is going to be (say 50 amp for example, add a 50amp breaker in here and hook your feed from the main panel to that breaker
