If it is #4 copper it it properly sized for a 100 amp service per NEC 310.15(B)(6)
Interesting!! Our codes list various types of #4: TW- 70 amps; RW75, TW75- 85 amps; R90, RW90, T90nylon-85 amps. We don’t even get close to 100 amps.
I am opening a small restaurant and I’m wondering if anyone could help me with the calculations. I don’t want to upgrade to a 200amp panel if I don’t need to. The following is what I will be using:
dishwasher - 208 V…40 amps
showcase - 120 V…11 amps
cooler with sink - 115V …8 amps
single door cooler - 115 V…8 amps
2 domestic ranges
two stainless steel Bunn hot water tank
one Bunn coffee machine - single burner
two food processors
one toaster
one toaster oven (small)
one microwave
one crock pot
I will be using beaters periodically
cash register
one small fan (possibly needed during the summer months)
one air conditioner
I will be needing a chest freezer in the basement and also possibly a small fridge.
Any input would be greatly appreciated.
Exactly, once I had a client and their realtor try to pressure me into calling the 100 amp panel obsolete simply because they were going to remodel after purchase.
The house hadn’t been remodeled since it was built decades ago so 100 amps was fine.
I politely told them to take a hike. :roll:
You will want to consult with a professional electrician of your choice. This is an inspector forum. We don’t dispense that type of advice here.
