In my electrical panel, there are 2-15 amp breakers that have been ganged together and they were for used for supplying power to a large baseboard heater. I have removed the heater and will not be replacing it. I would rather run the wiring out to my shop for more power. Anyway, do the ganged 15 amp's equal 30 amps? If I run the power out to the shop, will I have theoretically 30 amps to the plug? It seems logical to me, but I would rather ask. Thanks.
