I have a 100 amp service, #4 copper wire supplies it underground and so I don't think I can put in a larger main breaker unless a new service is installed. I would like to check the probably future load on the service to help aid in deciding about putting in a new service, which would involve going across the street and would be quite expensive.
I'm trying to calc using an book I have on wiring. This is just for my own thinking; a real electrician would be involved in the final decision.
The home is a 2500 SF house in CA. All of the major electrical appliances will be gas. Half of the home has been remodelled to code and the other half will be.
watts Home SF 2500 sf x 3 7500 Kitchen 4 x 1500 6000 Dishwasher 1 x 1500 1500 Disposal 1 x 900 900 Laundry 1 x 1500 1500 Total 17400
First 10000 10000
40% of balance 2960 Load calc subtotal 12960 Furnace 1 x 1800 1800 Load in watts 14760 Load in amps 61.5Anything that is obviously wrong with this calc?
Thanks
