    Have you done a load determination? Most lights and pumps of this nature are well below 50 amps.

    2 of the 3 amps will be running at 80% and the third 60-75% depending what I add this year. The forth will just have the 3 pond pumps on them, so very low as they all run on a 16 gauge extension cord without issue.

    That is way more than enough.

    Both these types of loads would be considered "continuous loads", as they would be expected to run for three hours or more.

    Four 15A 120V breakers can supply a continuous load of 5760 watts.
    A 50A 120/240V feeder can supply a continuous load of 9600 watts.

Main panel and sub panel breakers [ 1 Answers ]

I inspected a sub panel fed with a number 4 copper cable. The main panel breaker was a 90 amp breaker, but the sub panel breaker was a 100 amp breaker. Is this OK?

60 Amp Panel.how many breakers? [ 2 Answers ]

I recently bought a house with an old Federal Pacific Panel in it. (Yes yes I know, major fire hazard.) I was just wondering, it is rated as a 60 amp panel, does that mean that the sum of all the breakers must be less than 60 amps, or that no one breaker can exceed 60 amps?
