metal conduit Running multiple singles through a metal clad box

[kevytee]

Hi . Im running some conduit , a long horizontal with metal clad boxes , with vertical runs to a term box for light fittings and a couple of smoke alarms . Was going to use 4 way boxes dropping down to the sockets and up to the light s. Is it acceptable to run them through the metal clad boxes and cut out the 4 way boxes . Its 4mm radial with loop in lights and feed for smokes . Im thinking no but it would be neater and of course cheaper . Seem to remember that its bad practise to run cables theough accessory boxes .

Any thoughts or experiences gratefully recieved

Would you not be better using 50 x 50 trunking for the horizontal run and take your conduits from the trunking to the accessories
