This brand new service is a thing of beauty. I am very proud of the crew!

There is now 400 Amperes available to this 6 unit condominium building. Each unit has a new 100 Amp, 120/240v circuit breaker panel complete with new GE circuit breakers in 15 and 20 Amp sizes, as well as 30 Amp 240v breakers as necessary. Previous to this, they had very small 6-circuit panels that had no room for rewiring or future expansion. Owners could not add new circuits because the existing undersized circuit breaker panels were all full. There was no room for expansion. Also, new GE panels allow the code-mandated AFCI circuit breakers that must feed bedroom circuits to be added.  There are now AFCI circuit breakers available for these 60 year-old Wadsworth panels that we pulled out.

The conduits are all individually custom measured and bent to fit into the space. Large pull-boxes and troughs allow us to transfer the wiring from the old locations to the new ones.

This building will be all set for the next 50 years!

PICTURES:

Top- 2" parallel Rigid Conduit Risers Bring the main power into the building.

2nd: Main power conduits enter the Main service disconnect from the back. On the left side, the 400Amp circuit breaker in the cabinet serves as the main disconnect for The entire building. Modular metering to the right measures current use. (Old meters hung for ComEd to easily take when new meters arrive)

3rd:

All the brand new panels. The troughs (Long grey metal rectangular enclosures) above the panels carry the branch circuit wires that go up to the units. The troughs below the panels carry the main power cables feeding each individual panels.

4th:

The row of 7 vertical 1" conduits corresponds to the 7 100-Amp panels. Each 1" conduit carries the feeder cables for one of the panels. At the opposite side, these cables originate in the meter housing, where they bring the power from.

5th:

The clean wall where the original little panels had been previously installed.

This North Side Condominium association was a pleasure to work for. Most of our new services are on the South Side, either in Hyde Park or the surrounding communities. It was nice to work in Lakeview. And As I said, these clients could not have been nicer.
