The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires or, more commonly, #2 aluminum wires, for example. (Aluminum is often used for feeder cables because the cost is typically much lower than that of copper wires.)

How many circuits can you have on a 100 amp service?



Typical 100-amp panels have 20 circuits, meaning they can handle 20 full-sized breakers. 20/24 panels can hold 16 full-sized and 4 twin breakers (24 circuits in total). The number of breakers can max out to 30-42, too, depending on the design of your 100-amp pane.

Can you feed a 100 amp sub panel with a 50 amp breaker?

Just wire it up. There is no problem using a sub panel that can take more current than you will ever feed it. Points to note: The cable to your hot tub will be rated for 50A (not 100A); therefore you must not upgrade the breaker in your main panel to 100A.

How many 20 amp breakers can I put in a 100 amp panel?
