ECN Forum Forums General Topics of the Trade General Discussion Area 320A MB into 2 200A MDPs?

They would not be parallel one set of 3/0 to each panel, to be parellel both ends would need to be connected together.

To come off the 400 disco and run to the panels you will have to apply 240.21(B)(2) and keep the length under 25'

The panels have 200 Amp MCBs right?

Yes, the two 200A Discos is the way I'll go with this, thanks.

Got the materials quote today, and looks like the materials will come closer to $1700 (deflation?) and I'll keep the labor in the 80 man-hour range as well.

Figure I'll ask for $3500, then let 'em drop me to $3300 so they'll feel good about themselves.

Yes, the panels will have MCBs.

Thanks for all the help!

Thanks for the correction.....must be a senior moment. My fingers did not type what my brain sent to them.

I am quoting a similar service in which I am using a 400/320 amp meter main panel which has twin 200 amp breakers in it. It goes for around $500 where I am. Just a thought that it might save you some labor and time on the job.

this one i done quite a bit with large redistal home as long the breaker box is not over 6 feet from meter pedstel or socket this what i ran .

2- 200A 42 space boxes
2X 4/0 al wires (3 conducters)
a length of wireway thru then spit off with 2 inch conducts nipple each side of wireway and single ground wire 1/0 size or duplex ground wire #2 each

for labour wise it is 60 man hours ave but it can change depend on what it have on the strucure and location ( my most have basement) cost wise i really cant say it depend on what it setup and if any sub feed box are involved or not

i hope it can help you with that but if any question just drop the line here
