Back To The Service

Posted on/at 7:37 PM by Sparky

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.

Hi! my husband is an electrical engineer here in the Philippines. Your stuff are similar to his staff. He presently supply a 2 units of 1000KVA generator set and a synchonizing panel to one of the company here.
