Wiring Electrical Service Changes


By Dave Rongey - Summary:

Careful Planning for Electrical Service Changes: All circuit wire conductor types and sizes must be properly protected by an over current device or circuit breaker.

Electrical Service Panel

Electrical Question: At our office we have a 3 phase electrical service. There are three 110 volt lines that come from the electric meter can to a breaker. Then out of the breaker to the panel box. We also own another office bay next door, and the meter can for that is next to the first office in the bank of meters. This office does not have a meter and is dead. We have permission to run both offices of the first meter can feed. Here is what I did. I disconnected the 3 wires that were connected to the bottom of the breaker of the dead can, and spliced them accordingly to the 3 wires coming from the bottom of the breaker on the live can. I also carried over the ground wire. The one office works as normal, but the other office does nothing. What am I missing? I can send a hand drawn diagram if you like. Your help is needed.

This electrical wiring question came from: Neil, from Cancun, Mexico.

Dave The Electrician’s Reply:
Thanks for your electrical wiring question Neil.

Careful Planning for Electrical Service Changes

Please be advised that this is a question from Mexico dealing with an electrical service that is not typical for Residential or Home Electrical Services in the U.S.A.
