Wiring method for Mfd Home

[kar108]

A 100 amp disconnect is located inside a mfd. home below the meter base. It is connected to the meter base with 3 insulated conductors. The wiring from the 100 amp disconnect to the breaker panel in the permanently installed mfd home uses jacketed SE cable with 2 insulated conductors and a bare braided neutral - all aluminum. The aluminum neutral is covered with heat shrunk insulation inside the panel but not the disconnect. The grounding conductor is a #6 bare copper wire from the panel to a terminal block in the disconnect panel. The frame of the home is connected to the same terminal block which is then connected to a ground rod outside near the meter base. Is this wiring method acceptable?

Re: Wiring method for Mfd Home

are neutrals ever allowed to be bare wire past the service entry point?

It's a little odd there's no mention of the outer conductor in the SE Article. Maybe you could look at the neutral conductor as being "well stripped"

I take it that the separate equipment grounding conductor is bonded to the breaker panel and the grounded conductor is not.
250.134 requires the equipment ground to be in the same cable as the feeder wires.

I'm thinking it's in conduit and that's EGC.

EGC is not in conduit - stapled to runner board next to SE cable.

Yukk, it's like everything's good to the disconncet, then, yukk. A piece of NM?

Although this doesn't necessarily sound unsafe, it doesn't sound NEC compliant.

I'm thinking somebody did this wrong and somebody else came along and said "what in tarnation?" "You dont have a ground".
