Feeder Cables

[Steven Brewster]

Jeff,

I totally agree. But as I mentioned, see this all the time and no one around her seems real concerned.

Same scenario seen on todays inspection, 3-wire no ground to interior panel, neutrals and grounding conductors on same bus, panel not bonded fed by 100amp breaker from the 6 throw disconnect beneath meter. I guess were just hopeless here in the hills. Well, got to go slop the pigs!

Find it all the time and the AHJ and all electricians will tell you the 3-wire original panel is a grandfathered installation. In other words, they will not require a 4-wire feed be installed in the remote panel.

Now, if it is a new permitted installation of a remote panel, a 4-wire feed is required. But in actuality, I rarely find them done correctly.

Anyway, this panel should have been a 4-wire feed from the SE and I always write it up.

Steven, how do you write up the "missing" 4th wire in the subpanel in this case?

A 4 wire feed has 3 hots and one neutral. What would a house be 3 phase.

A 4 wire setup to a Sub-Panel ( Remote Distribution Panel ) does not have "3" hots...it has (2) Ungrounded(HOT) conductors, (1) Grounded and (1) Grounding(EGC) to the secondary enclosure.

The missing wire peter is speaking of is the "EGC" or Grounding Conductor for that SUB-PANEL ( Remote Distribution Panel ) as the statement was the main panel is now outside and it feeds the interior panel.

Thanks Paul for the clarification. So how would "Paul" write this up?
( I have writer's block).
