I came upon a job recently where the electrician needed to install a 200 Amp 3 phase subpanel.So he grabbed 100 Amps from each of 2 seperate 3 phase panels which are side by side,but on 2 differant meters. Is this outragous or what?Maybe it is typical workmanlike behavior.But it seems to actually be another friday afternoon job.:-?
 
its perfectly fine! code allows you to parallel feeders. you guys are just a bunch of hacks trying to take advantage of the customer by selling them a bigger service.

(is whats going through the head of the guy who did this)


i would have loved to seen that go boom if he got a phase swapped
 
This is highly dangerous for multiple reasons, one how do you go about shutting down the 200 amp panel ? second how do you keep the first panel from back feeding into the second panel and causing a potential hazard ?
 
Jesse,

This needs to be brought to the attention of the Electrical Inspector, or POCO , asap. This

booby trap could kill the 'meter person " who may need to work on the meter. If you are

not willing to get involved, make a call without giving your name. YOU MUST DO SOMETHING.

Jesse, make sure you are right, then do the right thing.

How does he make sure the current is evenly divided? :confused: :)wink:)


Some peoples' children! :rolleyes:
 
Thanks guys for the input.The responses were very confirming.I have removed this panel already.I informed the customer of the huge danger I felt about the situation and then began the demolition.I just wanted to make sure I wasnt out of my mind...forgeting some extraneous code about equipment fed from more than one source with parallel feeders or some such thing.But...I guess Im not as dumb as I thought I was.
 
Jesse,

Removing the sub-panel is a Good decision!

The potential for Back Feeding is Deadly Dangerous!

Results like this thread make the forum very useful.

An electrician did not do that. He may have fancied himself an electrician, but most assuredly he was not.
