Is there a NEC requirement for maximum number of outlets 120V 20a in a detached garage? I understand the load requirement, but I had thought I had read somewhere where there is a max number of outlets per breaker?

Is it okay to use a 100 amp subpanel main breaker panel in the garage coming from the split 200 amp main breakers? or do I need to have a 200 amp main breaker panel in the garage? Also what would be the max allowed 120v 20 amp outlets would be allowed on a 20 amp breaker?

I got a call back today from the poco, and they said my existing bkr panel is good to go for 400 amp service, and that there requirements are different than mine regarding wire thickness. I mentioned the tamperproof wires and they said it was a felony to remove, but they would send out a tech to...

Ouch, I didnt want to hear that!

So I pulled off the left side of the breaker panel and the Poco incoming feeders are 4/0 aluminum, and the meter has CL200 on the faceplate. Will I be responsible for the cost to have this upgraded for higher amperage from the Poco? Any recommendations? Thanks for the help, it is a bit on...

Sorry, the full panel part# is HP404040SH. The wire has 3/0 on the jacket and its copper stranded wire. You can see it in the picture from one of the earlier posts. The microwave and oven are combined, and I got the amp rating from the manual of the unit online.

So how do I calculate what size subpanel could be used given the actual loads I had listed?

The 3/0 from meter to the split 200a breakers. It is a Cutler Hammer HP4040 I was just questioning feeding 2 200amp breakers with 3/0, since it is not rated for 400 amps, as far as I can tell.

I updated the load sheets, I made a few mistakes. It is really hard to keep under the upload file size!

Sorry about that, not used to keeping docs so small.

I made up a spreadsheet of the loads. Given the split breaker design, is it feasable to have a 125 amp sub panel for the garage? What do you recommend?

No heat/ac/water heater in garage, I will probably just use a portable swamp cooler for awhile. The house is 2850 sq ft, being in phx area running a/c throughout the summer is on all of the time. Since the main breaker is split, and the supply is from 3/0 wire, am I constrained to about 225 a...

Yes, they are bkr sizes

I added a pic of the main bkr panel, design loads, and single line diagram.

I edited the last post with house loads.

The design load for the house from the electrical schematic shows 157 amps. 2 a/c 70a, range 50a, refrig 20a, dryer 40a, washer 20a, water heater 30a, dishwasher 20a The garage will have 2 post lift 30a, welder 40a, plasma 30a, compressor 30a, Mainly one man shop, with the exception of a...

I am planning on wiring a sub panel for my 40x60 detached garage. On my house, I have a 200A/200A Split Main Breaker Panel with 3/0 AWG wire feeding the split main breakers. The 2nd breaker is unused. How do I determine what capacity sub panel I will be able to install? Thanks, Brent
