I received a pricey estimate for a NEMA 14-50 installation because I apparently need an automatic transfer switch. Now I think I will go with a NEMA 14-30 DIY install instead. I am just wondering if my breaker will be able to handle the load without any issues. Also, the electrician said my home currently has an 88 amp load, and the addition of a 14-50 would raise that to about 112 amps. What would a 14-30 raise it to?
I plan on using this outlet mainly at night to charge my EV. I want to use 10 AWG Romex SIMpull NMD90 (10/3), routed from my breaker in the basement to my garage.
Edit: @Harper @machavity Sorry for the late response, the system wasn’t letting me for some reason. I don’t know how to do a load calculation myself (haven’t understood how to do it properly based on whaf I’ve searched online) so I’ve just mentioned what my electrician said. I have an Eaton breaker. Here are some pics: https://imgur.com/gallery/KYHLdjO
The major appliances that I can think of are: fridge, dryer, washer, air conditioner (only during summer), heater (fall/winter), furnace.
