Mounting A CT Cabinet

Today we mounted the CT cabinet on the wall and drove our ground rods. All we need now is the distribution panel then we can get our inspections in order to get power turned on. This location for the service would not have been my choice, however the power company whom has the final say are the ones who choose this location due to its proximity to their pole.

If you have been following my blog I had posted about ARC Flash on 10-4-08. Today we talked about what we are required to do. As far as what myself It looks as though I need to get a new set of hand tools rated for 1000 volts our company
provides everything else.

NFPA 70E Compliance

Back To The Service

Well today I had to go and pick up our CT cabinet we have been waiting for for almost 2 months now.There really isn't a whole lot to a CT cabinet.
The Ct is a Current Transformer, The current transformer safely isolates measurement and control circuitry from the high voltages typically present on the circuit being measured. This installation is 1000 amps that is why we needed the ct cabinet.






This is a typical wiring diagram of a CT cabinet, it is pretty close to the one we have.This is the biggest residential service I have ever built, a few years back we did install a 800 amp service and I had thought that was huge at the time. Yesterday I was sort of short with my blog due to working late and all, we had to replace a 1000' pull of wire between the local mall and the pump station that houses all of the sprinkler pumps for the mall. Then once we got the wire in we had to determine what the former electricians had done since none of the 16 wires were labeled correctly or even the same on both ends.
