Electricity Is On

What a week we had, The other day a freak snow storm blew through the area creating a white out long enough to cause a major wreck on the interstate closing it down a few hours and in turn making driving around here a nightmare. yesterday went a little smoother though we finally got the 1000 amp service going at the old farmhouse. Then of course we had to start removing all of the old overhead wiring from years gone by. We will be a few days getting all of the old stuff cleaned up and of course the weather is not looking good for the beginning of the week.

Hard Days Work

What a day we had, today we were met with this obstacle directly in our way. If we didnt have the trench 90% done we could have went a different direction, however it was quicker to move this rock than dig about 100 feet of new trench to get around other obstacles. I was very surprised we even got this monster out of our way. The engineer from the power company stopped by today to set up a time for a hook up on our new service. That will pretty much complete the 1000 amp service on the farmhouse.

Service

Today we pulled the wire between the farmhouse and our service. We had 3 pulls that are very long but it went well and that part is done now. Tomorrow after a few hours I can try and call in for my inspection if everything goes ok. We have done a lot in this house in the last few months, we still have a lot to do also. Now we can concentrate on retiring the old service we are still using as temporary power. We used our new wire puller and it worked really good, our old one used to take a long time to set up this new one is pretty fast to set up and worked without a flaw.

Building The Service

The back box to our panel finally came the other day and today we finally set it in place. Now comes the fun part of pulling 250 XHHW from here to the house X3. Once we get the wire pulled and I can get everything terminated we will be one step closer to getting some permanent power turned on. This job has been a lot of fun because nothing on it has been normal.

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.

There is a training video here.

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.
