But you could use multiple extension leads from a 4 way thats powered via the trip if your worried.
Does depend on the capacity and the length of the cable though.[/quote]
It probably would be Ok, but adding things does cause a higher resistance & if it's someone who doesn't know much about electricity other than it makes things work, then it's best to run on the safe side.
They might not notice a long cable starting to overheat & becoming a hazard.
Just a quick note to the OP, don't plug multi sockets or 2/3 way adaptors into one another.
