Wylex ESE2 Insulated Electrical Circuit Breaker Enclosure - 2 Module, white

Good value, looks smart and the smallest unit I could find.Will hold a 3 slot module even though it says 2, the open section has knockouts that can be snapped with pliers to make it bigger.

Great kit just for reference the cable preset areas for holes are at the top and bottom, not the back. I might have missed this but it wasn't clear to me at the time. I ended up just cutting a hole in the back anyway and feeding cable through

Bought this to fit a transformer I purchased for a ring wired doorbell. Solid piece and advertised with the transformer however glad I measured before install as the transformer front which should pass through the hole at the front was slightly larger. Thankfully this is plastic so was able to shave the hole bigger and it worked a treat after that.

Just what I needed, absolutely perfect for use with the Transformer supplied with the Ring Pro 2 doorbell, it replaced an old "Freadland" transformer that only supplied 12v, when most of these new doorbell's require 16/24v replaced within 10 minutes, the price too was really good, great make too, and delivered within 2 days Excellent service...

used this for a modbus meter and fits perfectly. Decent brand and good quality.

Used to fit a Ring Doorbell transformer. It does the job well, at a reasonable price. It's not very elegant, but that's fine for my use case as it's hidden. The cable holes need to be broken out, requiring a hammer and a screwdriver and quite a bit of force. They were removable without any damage to the rest of the casing.

Ring's equivalent is £16 and 5 times bigger than needed

I bought this to use with a miniature 4-channel lighting relay, but there wasn't enough space to get all the cabling in safely. I'm sure it will come in use for other projects requiring fewer cables.
