Hi
A few months back I posted a question regarding different methods of connecting lighting feeds and switch feeds at switches in singles conduit cable. My question was more from an eddy current perspective. I’m currently working on a job with steel trunking where the drops to switches and sockets etc from the steel trunking are in plastic conduit and the switches / sockets are plastic. My previous post queried whether having just live / switch live and earth down through a single hole in the trunking to the switch or live/neutral/earth supply to switch and live/neutral/earth out to the light through a single hole in the steel trunking was acceptable. I opted for the latter. My question now is can I take a permanent feed to the next switch from the previous switch? In effect I’ll have l/n/e supply to switch and l/n/e to the light and l/n/e to the next switch, so 9 cables at the switch position all through a single hole in the steel trunking. I know this method is used in domestic settings with t&e cable but singles in conduit has the flexibility of running each single cable directly where it needs to go but from an eddy current perspective having all my single cables through the single hole in the metal trunking down to the switch gives me peace of mind. Thanks in advance
