Using a RCD then this.

Only surge protected. Not RCD protected.

This.
Not suitable for out side use.

Are you sure? HPM make one the same with an RCD instead of the three pin plug. I have one. My one trips if there is a fault, as it should.

What the OP is doing is essentially the same as the HPM manufactured one without it being hardwired.

If you plug that box into a RCD, then all the outlets on that box will be RCD protected.

Or you can replace the 3 pin plug with a RCD type.

See pic on top right. :

There are some models of RCD plug that unlatch when they are removed from the supply, other types maintain continuity when unplugged.

I Question this, from a safety point of view, best get the ones that click out, so that you re test the circuit when you plug it back in, but then you should test them every so time, but how many do that ?.
Yes I do, but that's my manor, as I have had 1 fail to trip, . It was a faulty unit.

What if the Main-House has RCCB (residual-current circuit breaker) and you plug in an RCD (similar or same as link in post #9i) nto the Main-House wall socket, which one (RCCB or RCD) would detect fault first?

Does not matter, but milli seconds in it, so long as you use a rcd , then all good.

If your power circuit is RCD protected at the distribution board, then the plug in RCD's are unnecessary, unless they have a lower trip current. The most sensitive RCD will trip first. If both are the same rating then it will be anyone??

do a ramp test and see what one trips first. We have had some 30mA rcds trip at 12mA. Pain in the arse when lots of computers are plugged in all with earth leakage. (we replaced the unit)

Very informative & helpful, much appreciated.

The only problem I had was that I had a container with a de-humidifier inside, it was in a friends paddock, and on the end of an extension plugged into an outlet in his garage. If he used the outlet he didn't always remember to reset the RCD when he plugged it back in. So I replaced it with a non trip one.

your coming up short with all your posts,why would it not be suitable for outside if it's plugged into an rcd?your post in the farming section regarding single phase to 3 phase was amateur.stick to the garden diy son.your coming up short on the electrical.

Those boss multi boards are not suitable for outdoor use. The plugs face upwards which allows moisture, grit etc to enter the unit. They are not IP rated as well. The newer boss boards have a twist and close plug entry but still not IP rated.

yea the point I was making was,yes the box is rcd covered if plugged into an rcd plug not overload/surge only as aj was saying so fine to use outside as a multi box however not as a permanent weather protected PowerPoint.
