SIEMENSW0408ML1125U Load Center, Gray

Good box for my spa disconnect. Was able to install 40A GFCI breaker and pigtail. Just what I needed.

I’m a fan of Siemens gfci breakers and this is a great combination. Lots of knockouts in all the right places and very well built. Easily accommodated 240v hookup with a Siemens gfci.

If you buy this for anything but a service entrance disco you will need a grounding bar.

Installed at our gazebo

This review is specifically for the model W0408ML1125U panel. I suspect some that show up are for other models.First, you need to get the inner panel out of the box. I struggled with trying to twist and pull this out for quite a while, so hopefully this will save you the trouble. Lift the bottom of the panel slightly so it is higher than the screw terminal that's at the bottom, then use the big hole in the top to tap the top of the panel with a hammer. It came right out when I did that.Now you can put the cover on the hub hole if you want. The self-threading nut is a real pain but by pressing as you turn and going slowly it will probably work OK.Note that this box does not come with a ground bar. If you are using this as a subpanel or disconnect, you will need a ground bar to tie the box and the grounds for the inputs and outputs together separately from the neutral bus. I can't imagine anyone using this small box for a main service panel. The ground bar should be included.Some reviews say that the ECGB14 bus ( https://amzn.to/2QEE26a ) is right for this box. No it isn't. There actually isn't any right ground bus for this box, because there are no mounting holes provided that work with the self-tapping screws that came with it. Now to be fair, there is one hole that's covered with a sticker that might be right for some ground bus or another, but it was too big for the screws that came with this one. Fortunately I have a drill press and it wasn't difficult to drill holes where I wanted them. You may not be so fortunate.I used a QF260A GFCI breaker ( https://amzn.to/2ZLITX7 ) in this box for my spa. It meets the current code requirements. Amazon sells a Siemens unit with a 60A GFCI breaker, but it's unclear if it uses this later breaker or the older QF260 which doesn't have the self-test features. That's one of the reasons I ended up rolling my own. Also this box give me two spots for auxiliary circuits in case I need them (as long as I provide the proper wire to feed it from my panel).The screw in the neutral bus grounding kit with the large head fits the bottom part to hold the inner panel in place. It can be hard to get started because it's self-threading.If you don't know whether to ground your neutral bus or not, talk to an electrician before using this.

I used this as a disconnect box and to supply power for a separate outdoor gfci outlet box. The circuit breakers purchased separately worked perfect.I had to make a separate trip to the store to purchase a ground bar which i think should be included as this box rarely would be used to combine neutral and equipment ground together.

I used this as a disconnect for two mini splits that were right next to each other so that I would only have to take up two slots in my main panel. I actually prefer it over a standard disconnect.

Excellent.
