...Usually I would tell people to be wary of Rolec as some of their cheaper models aren't quite waterproof...

Not quite waterproof isn't the main concern with these, here in UK. This is the biggy:

Both these Rolec-branded RCBO deserve to go in the bin asap, imho. And get replaced by Garo or other reputable brand item. Then you end up with an easily maintained & repaired EVSE.

That green-labelled one is what they replaced the blue one with, I believe. And we've seen 2 or maybe 3 failures of these, as per the pic. Looks like they're continuing to cheapskate wrt the RCBOs they use.
