Excellent Disconnect GFCI box for your Hot Tub, reason being that there is spacious room to run the 6 gauge wire that requires bending for connections, the white pigtail measured 19" in length, which worked great with my power in white wire that was 6", so 6 x3 =18, the 19" gave me 1" over the thumb rule the pigtail has to 3 times longer than the incoming white wire length. This sounds like a crazy thumb rule but was told this by an electrician, take it for what it is worth.
