thanks guys.. the help has been useful..

I submitted the information to the 1st person and it then went to the engineer.. I sent over an email explaining the situation with the paperwork and got a much better response.

I have since gotten the Metersocket had to order 1 more 200amp for dual 200's.. I like the design of the panel.. Not quite as good as the SqD but think it will work very well.

, ordered the MCM 500 copper 390ft, also had to scrounge for some 4" PVC Sch40 and 2, 4" rigid straight (rmc) and 1, 4" 36" sweep..

I have a pvc sweep on order and need to pick up a few more odds and ends.

the engineer came out and I gave him a show of the shop and explained what will be taking place.. I don't think he really even cared.. He did mention why I didn't ask for 3 phase and explained the RPC.. He then said, good thing because in front was only a 1 wire high power line vs the 3 needed.. Or course he said, if the 3 lines were there, 3ph would have not been a problem.. LOL..


Also scrounged 100 pieces of 3/4" EMT..

Crazy how much all this stuff is now vs 2 or 3 years ago.

doesn't look like much $$$ until you buy it and then the pile is so small.

I went to RI for the PVC and to NH lake Winnipisaki from the RMC. 2 long days in a row.

Also, because the electrician won't be around till items are installed I asked the electrical inspector if it was ok to run the conduit and wire before pulling the permit (have to be a licensed electrician to pull a permit) he said yes..

I know of someone that got an ok from the city after everything was installed, but not from the power company they had to add a type of power tap box, it was a lot more work to add it later.... had to install a separate meter to feed the box then to the breakers was not able to use the combo meter setup.


You may want to ask "your power company" if they will require you to install a

(I don't know the exact name) its a "large" box that allows them to tap their equipment into the incoming lines to monitor power factor and usage, they have current transformers on each line.... also used to check calibration of the meter.

your city may not require it but the power company may.

Likely the difference between industrial and residential power requirements in this case it was a small Upholstery shop.

You would be surprised how many 3000-4000 sq foot homes are running 400 amp at meter base and disconnect then splitting and running 2-200 amp breaker boxes . Cheaper that way than a 400 amp box and all the wire runs to the end of the house .

I believe that is called a meter cabinet..

No need here at least for the time being. The rules are always in favor of the power company unless you run off grid.

There is an exclusion in the reg for NG that generators if and when installed the company has to be notified a certain time limit before disconneting from the grid.

I had to submit all the information to the Electric company and to the electrical inspector before any of it would move forwards.

I hate to dump the info on you. But here are the 3 documents that needed to be read to figure out what is needed.

in the 759b page 20 document there is a whole section on exactly what they deem as acceptable.

For sure.. it is interesting that 400amps is still not wide spread here..

It's also interesting that they call a true 320amp service a 400amp, but a true 400amp is another step up animal wise.

Good to see your persistence and perseverance is paying off, Jen!

Sometimes you gotta make a drive (or two) to get the job done... So electric by V-tines day?

at current levels above 400A it is impractical to safely pass that level of current thru a small stab-in meter,so direct wiring to the poco transformer(s) is accomplished thru a CT cabinet,then to the service entrance disconnect..current is metered thru CT's(current transformers) which live in the CT cabinet,usually a 30x36" double door steel enclosure with busbars inside..sometimes a standard meter is mounted outside that cabinet and reads the CT transformers,sometimes it's networked

what voltage is the 400 amps at?

Is it 400 amps at 110v or 400 amps at 220v?

thanks.. I'm hopeful it will happen any day.. I don't want to order the sand to early and have it freeze and definitely don't want to open the ground because of the high water table. Just knowing it will move forwards is a relief.

Great explanation.. Doesn't get any better than that..

It will be a 400Amps @ 240V but it's really a 320amps continuous. It can spike to 400amps..

I'm wondering what they will put in for a transformer.. When I start the RPC the lights would dim. No complaints, I'm wondering if they will pull it from the high line which only powers 1 house on the street at the very end.
