    Hi Charlie,

    Keep up the good job!

    I was asked by a friend "what's the max number of general purpose receptacles on a 20 amp circuit?" My answer to him was there's no limit. He told me its 20. So I went to find this info in the NEC article 210 but came up with nothing. Can you please help with this issue?
