Allowable Load

Allowable Load - for lack of a better term.

My 30yr old house has 150A service.
I currently have natural gas heat.
I'd like to install 2 to 4 elec baseboard heaters in a couple rooms.

As I understand, your appliance ampacity ratings can't theoretically overload your main service (whatever). And last year I added a 60A unattached garage.

Is there a (simple) online calculator I can used to determine if I can actually add ANY elec appliances? I was looking in a code book under allowable ampacity but got a little lost in the jargon.

You need to do a "demand load calculation". Google that term and you'll find enough information to do it. A number of home wiring books tell you how to do it too. We can help you with it if you get stuck.

P.S. "Ampacity" is the wrong word here.
