Your home's main circuit breaker identifies the amperage capacity of the electrical panel.  There will be a number on the electrical panel telling you what the amp capacity is.  For example, 100 or 150 could be listed beside the panel.  100 amp is the minimum allowed by today’s code.  150 amps, 200 amps, and 400 amps are among other standard available sizes.   What size do you need in your new or exisiting home or business?
