A comercial job I have been working

Well first things first, nice slide show. I have heard it said "you can't make a silk purse out of a sows ear" but it sure looks like you managed to come close to it. I like the distribution block in the trough for taps makes things simple. A+ job.
 
Nice presentation, but why not mount the trough higher, with the meters below it, and the discos below the meters?

Some reason you chose to do it with pieces and parts, rather than a meter stack with integral disconnects?

The meter sockets are issued by the light company and my boss informed me that they no longer issued multiple sockets as a meter bank/stack.

3 exsisting panels dictated how alot of this went. Also, I had to keep power going using the exsisting meter socket. I cant enter the gutter on the load side of anything.

How did you come up with that size?

We require a 500 amp service. 4 tennants @ 100 amps and a house @ 100 amps.
My code book is at work but if I remember correctly we would have had to use 500 mcm. The cost and the fact it would not have fit in the exsisting 2-1/2" riser , we chose to go parralel. If that is the wrong size to use, I will check into it. We have not installed those wires yet.

disconnect looks a bit high

That one disconnect that is higher than the rest is eye level with me and I am 6'. My concern would be that the far left and the far right meter sockets are too low. My boss says they are fine but I have seen post on this forum that 4' is required as a minimum by some local codes.

So you added up the size of the five disconnects?

Yes you can do that but you don't have to, by doing so you may have spent more then you had to.

If you did a load calculation and found that all the tennants and landlord combined was say 250 amps you would have only had to provide 250 amps worth of conductors.

Again, I am not saying what you did was wrong, just overkill. :smile:

I think it is a local thing here, but from what my boss tells me, they dont look at current load but at potential load. Considering 100 amps is the smallest service I can install, this building has the potential to require 500 amps.
