Daisy chaining a single phase socket from a 3-phase socket

[230V]

Is there any restriction on daisy chaining a single phase commando socket from a 3-phase commando socket. I know it's common to daisy chain multiple sockets of the same phase...but I am not sure about mixing single and 3-phase.
(The breaker and cable size is sufficient to allow this)...Thanks

I thought with the exception of the 16A size commando sockets weren't supposed to be on breakers higher than the rating of the socket.

you would also need a neutral to get 240V

We use three phase to single phase adaptor boxes at work these have pass through three phase and single phase sockets mounted on them so mixing isnt a problem, though these are pluggable as opposed to your intended hard wired route.

no problem whatsoever..

as long as the breaker rating is the right size ( IE 16A or 20A for a 16A socket, 32A or 40A for a 32A socket.. )

and as already said you'd need a neutral but if it's a 3P+N+E socket you're spuring off then you'll have one in there..

I got the answer I was looking for. Both single and 3-phase sockets are 32A and so is the breaker. So I shall go ahead with daisy chaining this additional single phase socket.
Thanks

Will the circuit withstand the proposed additional load?

What testing/certification are you going to do?

 

[ColJack]

the additional load is not an issue as long as it was designed to take the original load ( ie cable size ) and the breaker is not changed.. it just means that you can't use both sockets at full capacity without tripping the fuse..

in practice, a 32A 3phase plug is probably never used at capacity.. 25-27A is about the most that people will put on them before going up a size..
so he has a few amps spare for an extract etc..
