Rated 4 out of 5 by 1 reviewer.
Rated 4 out of 5 by Great fit for some applications This box worked great for a tight location, where I needed 3 separate 1 phase circuits, but I think it would get very busy in there if someone utilized the full 16 available with the dual circuit breakers that are available. Also think the manual would be less confusing if they used separate manuals for the two panels that are featured in the instructions, that are of different designs, but no big deal. Don't forget to pick up a bus for earth ground if you need one. I would say pretty good quality except to make sure you don't pull the lower positive bus out of place when tying in the inputs. Once the breakers are in it should stay put just fine. When you pick up your breakers, the 220v have spring clamps that attach to the bus and the lower rail, but the twin circuit 110v ones have a J shaped blade on bottom that hooks under the lower rail first, then clamp the top one. Threw me off at first because I thought they were for the other type box. Would help to have had some pre threaded holes for mounting the bus. September 23, 2014
