Mounts easy
This box mounts easy and breaker fit perfect, would have liked a little more room otherwise bottom of box for wire connections to bottom of hookup but was partially the install as cable was long enough to loop

Well made complete unit.
Had to replace a service disconnect switch on my daughters house. Hers was originally installed in 1952 (!) This worked great and was a complete kit with breakers, box, and bus terminal. Heavy, well built, and looks good for what it is. Very happy with it so far.

Good quality, not easy to install.
If you have experience installing a load center with tight quarters, then this is an excellent choice. If you are a novice, this will be a difficult installation. I'm not saying that you won't be able to do it, just be ready to spend plenty of time to get it right.

Not big enough for GFI breakers
I made sure to ask and search for the question if this enclosure would accommodate a 60 amp gfi circuit breaker. And was told it does. While it technically does accommodate the breaker it does NOT leave enough room to also accommodate the wire bending and attachment at the bottom of the gfi breaker. I did get it to work, but had to remove the panel's front door clasp and also had to to crimp the wires to do so. 50 amp may be ok, but don't try using this enclosure with a 60 amp.

Doesn't include a ground bar
I guess this might be partially my fault for not looking closer... but there's no ground bar included with this bad boy. I was all excited to get my hot tub started up, but I had to drive to the store and buy a ground bar, because it's a no-no to mix grounds and neutrals in a subpanel. I have to admit, I was half-tempted to do some jerry-rigging, but it's not a good idea to mess with electricity and water. After adding the ground bar, which was very easy and cost like $3, this setup is working great. The box is heavy and feels to be of great quality.

60amp
I bought the smaller 60amp model. I am a huge fan of Siemens panels. It's rated for 4 circuits, so you can use tandem breakers, as it only has 2 slots. It does not come with a grounding terminal bar, which seems stupid for something that is obviously going to be used as a sub-panel, since it is a lug panel. The panel also has a limitation on either a gfci double pole breaker or afci double pole. Also there is not a good place to put in a grounding terminal. It's very small and very tight. Also the picture of the small 60 amp panel does not show this, but the screw holding the inner panel, has a 2 position tab at the bottom, that can be turned around, and allow the box to be locked.

Excellent for my purpose
Great load centre. Strangely it did not have a grounding bar/bus for the bare ground wires. I had 1 spare and added it. It did have a tie bar for grounding the enclosure to neutral bus bar. Takes Siemens type Q breakers

Worked well for us
I used this box in a temporary supply to some outside lighting. The supply came from one phase of a 220V 3 phase circuit, that has a 30A breaker. This box allowed me to create two separate circuits with 15A breakers for the lighting. It also kept everything in the box dry.

Works as intended
Superb product but it’s so annoying to work in for its size but that has nothing to do with the product.Great quality and recommend it highly!

Amazon match did not fit
The box did fit the GFCI but the distance from the GfCI to the bottom of the box was so close that it was impossible to connect the wires had to go and buy larger enclosure.......55 dollar waste
