5 Way Miniature Circuit Breakers with Distribution Box - IP65 Waterproof Distribution Protection Box with AC Leak Switch 40A, AC Disconnect Switch 10A+16A for Home/Office

I wanted to get protected power out to one of my sheds, and this seemed like the right thing. It's working great for me. GFCI and a couple of circuits, one for lights and one to plug in to. The box is a little tight to work with, but I managed to get it installed without too much swearing. Having to pry out the grounding bar was a little annoying, I had to be careful not to break something. You have to drill/cut out the wire holes that you want to use. Some of them are more difficult to use than others, so plan accordingly. It comes with two glands and two rubber grommets to fit the holes, I added a third gland that I had. The main cover seal seems good, and the breaker cover does well enough though it's less water resistant. It did well enough in a shower test that I'm not worried, especially as I'm installing it under a roof. The box seems fairly robust and should stand up to some abuse. Like others have mentioned, this seems to be made for the European market but it's working fine for me in the shed. I like the mini breakers and small boxes, they don't take up a lot of space.

I purchased this compact breaker panel for use in our little cargo/camper trailer. I installed an RV 30A input plug and fed it into this panel. From there it was a simple matter of connecting and routing the various AC outputs to be used inside the trailer. This little box was surprisingly inexpensive and well thought out. This version came with a single input disconnect breaker, and GFCI circuit of some sort, and 5 additional output breakers sized 32A, 20A, 16A, 10A, and 10A. The unit is very modular. All breakers are DIN rail mounted. The ground and neutral bars are nicely mounted on their own removable rail. Like any electrical breaker panel, this one has a nice fitting cover as well as a nice, clear "window" access cover. I'm not familiar with these little breakers but they look well made and feel good when operated. This panel reminds me a lot of the type panels I would see used in hotel rooms throughout Asia. Other size breakers are readily available and easily interchanged. The enclosure itself is marked all the way around with multi-sized "knock outs". They don't really "knock out" that easily. It is a plastic box, so a step-bit made quick work of opening the holes I needed for the conduit connectors. (It came with two strain-relieving sealing connectors, but I didn't use them.) There's plenty of room inside if you route your incoming wires carefully. The back of the box is also marked for mounting holes. I pre-drilled all four and used wood screws to mount it directly to the interior trailer wall. I also purchased and installed one of those in-line breaker input copper buss bars. This was much cleaner and simpler than making a bunch of breaker to breaker loops on the inputs. The description calls it an "8-way" box. Well, it has 8 terminals on the bottom side of the devices, but only 6 breakers total, so that's just a main + 5 breaker panel. That's plenty for my application, but don't be expecting 8 output breakers or something like that. It's clean, it's simple, it's easy to work with, and very affordable. If you need to add some AC distribution in some sort of vehicle or shed, this compact unit is well suited for it. Also, be sure to consult some electrical code or guidelines for proper wire sizes, breaker sizes, etc. for your particular application.

The CHENGPI 5 Way Miniature Circuit Breakers with Distribution Box may be a good product for Europe but it is generally not appropriate for the US. The Circuit breakers are single pole, 230V at 50Hz. The included breakers take up 4.5 of the 5 slot enclosure. The enclosure provides two, 5-screw bus bars.The enclosure relies on two gaskets to make it waterproof, one where the front attaches to the back of the case and another for the clear door flap. A simple squeeze of the door latch provides access to the breakers. There is nothing to secure the access door further. Ample knockouts are provided around the case but there is none in the back. The mounting holes need to be punched out if used and you'll need to find a way to seal them. I haven't gotten the bus bars out yet but will need to remove them to access the top, two mounting hole locations.

Unfortunately, this is a bit of a pickle. I'd love to leverage this but the problem is that this is rated for Europe and not for the US. This means if I install it, wherever that may be, will be out of compliance / code. There in lies the issue and while it could technically work for my needs, it doesn't comply to local code standards from a certification standpoint so it'll just go to the electonics graveyard.

I saw there was no Authorized Testing Agency marking or international marking. These would be Underwriters Laboratory (U.S.), CSA (Canadian) and TUV (German). Any of these markings and it would have been tested to the specifications it claimed. It could not be used commercially, but individually, it is ok. OSHA doesn't cover you in your home. All in all, it seems to be a well made little micro breaker. I installed it on my Conex that I use for storage. I needed power for a dehumidifier and for power to the battery tender for my dually that I park near it. It seems to have the ability to trip on overcurrent at 120V, I tested it with some equipment I have. I gave it 2 stars for the tightness of the box, no testing agency and the fact there was no instructions included with it.. I was able to remove the ground lugs and was going to reposition them on the bottom, but the lower part of the main breaker didn't allow me to install it there.

I'm basically using this as a solar disconnect, works fine for that but not rated for USA - AC - we're also doing low voltage DC solar, anything high and I would worry about arcs. box is a pain to deal with, work slow.
