For cables coming out of a CU and running where someone getting tools on and off a shelf next to the CU may knock against the cable if careless. I'm intending to give them some basic protection by putting trunking over them. The cables coming out the side of the CU go through non-combustible glands. However since the trunking will come right up close to the side of the CU it would of course still get extremely hot if there was a fire in the CU.
Would you suggest using non-combustible trunking, or having the trunking start where the glands end (so an inch and a bit away from the side of the CU, the glands are not metal so won't conduct heat too much), or not worry about it and use regular trunking?
If you think non-combustible trunking is the way to go where would you recommend getting it, and is there a non-metal option (mostly for ease of use)?
