2023年2月6日 · @tracyrobert Even if you put a double pole 60 ampere breaker in the main panel to protect the new panel feeder, you can still install a 100 ampere panel as the second panel. As Retired Master Electrician points out, the panel rating is the maximum the panel can be used for, not what it has to be used for. As for the service upgrade...

The terminals in the sub panel where the conductors will connect. We'll then use the lowest value, or 60°C if any of the above are not labeled. Once we know the size of the overcurrent devices, and the lowest temperature rating, we can use Table 310.15(B)(16) to determine the conductor size and material we'll need.

What wire size for 100 Amp sub panel 100ft from the 200 Amp main panel? Do I have to buy all 3 wires (2 hot and 1 neutral) the same size? Or can neutral wire be smaller size?

2022年10月5日 · Only lost sight of the "run 100 amp service" part at the end there. If Judson is planning 100A outside, unsure if the 200A meter main still makes sense. I imagined someone throwing a nice big panelboard on to existing cable.

2024年9月27日 · I have 1 1/2" conduit off that to my structure ~200 feet going to a 100 AMP panel. The wire my electrician told me to use for this is 2-2-2-4 URD aluminum wire. I have it pulled and the conduit all closed off into the 100 amp panel. The panel is a square D Homline 100 AMP 24-space, 48 circuit indoor Main (Home depot-HOM2448M100PCVP)

2018年3月25日 · The sub panel is a 100A box doesn’t have a main breaker. If I have 50A in the main, how high can I go in both panels to get the power I need without creating issues? The breaker that powers my garage right now is 50A with E18679 (ul) AWG 8 cu 3 CDR with AWG10 ground type Hm-B 600volts wire connecting the sub to the main.

2020年7月21日 · Then inside this panel, stick a 100A breaker, then run 1 AWG aluminum wire from there to the old 100A panel. The old panel must be re-configured as a subpanel, which requires removing all ground wires from the neutral bar, putting them on an accessory ground bar, and removing the neutral-ground bond.

2015年9月11日 · However, if your service and main breaker are 100 amps, you are still limited to 100 amps total. If you are adding enough large loads in the garage to need a 100 amp subpanel, you may regularly trip your main breaker and shutoff all your power - which means you would need to upgrade the service and main panel to provide enough power for everything.

2019年8月20日 · This got a bit long but to provide an example I just added a new branch circuit to a panel that by the total breaker value was 320a even after adding this new load (30 amp double pole) my measured draw for 30 days did not exceed 70% (larger measurement system used) this measurement shows I could safely add another double pole 15 amps to that ...

2019年11月13日 · I'm looking to run a 100 amp line from my 200A main breaker box to a subpanel in my new detached garage. The run is about 120 ft. A large part of the run will be under my house in a crawl space... the rest will be below ground. The garage will charge my car and power some equipment, possibly at the same time.
