6mm T&E cable routing requirements
I've just installed an electric shower. The 6mm T&E cable runs from the
loft down through an unheated airing cupboard. Does the cable have to be inside trunking or conduit where it runs through the airing cupboard, or can I simply staple it to the back of the cupboard's door frame, using cable clips like this: http://tinyurl.com/nllh2b2 Many thanks for any clarification..

Jim In general, no, it does not need to be in trunking. Doing so will mean the cable will get a slightly lower rating compared to being in free air (clipped-direct method). However, if you have a reason to suspect the cable will get clouted by hard things in normal use of the cupboard, then it should be protected (installation appropriate to the environment). It's not a hard and fast rule, you will need to assess it. Cables are normally surface mounted and clipped in airing cupboards, if you want a "how's it normally done" baseline :) |

I agree with what Tim and John said. But is the correct name for an unheated airing cupboard just "cupboard"? -- Adam |

Also, make sure you route it such that no clothes, towels, or other fabrics can be piled in contact with it. The cable needs to be ventilated. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

May need to derate for higher ambient temperature (I assume 40C would be a safe ceiling for an airing cupboard). |

email.me: But is the correct name for an unheated airing cupboard just "cupboard"? In my case it is a cupboard with a doorway but no actual door. So the slatted shelves are open to the air on landing, apart from a curtain which I draw accross if a guest is in the house! Jim |

6mm T&E cable routing requirements
Please may I ask, what power rating is the shower?
I was thinking of installing an electric shower as a back-up to the aging combi boiler. I thought that 10.5kW was the most powerful electric shower, so I went to TLC's calculator and typed in 11kW and 12 metres of cable, clipped direct. The calculators aid 6mm^2 would be fine; I was expecting to have to run 10mm^2 cable. Sorry to hijack the post. It's too late for the OP as he has already installed 6mm^2 but for everyone else, should you use 6mm^2 or 10mm^2 cable for showers? Thanks, Stephen. |

Oh, more detail? ;-) It depends on the circumstances; primarily the rating of the shower, and the length and nature of the cable route.

My local council powered its street lamps with 'clipped direct' to a barbed wire fence for a 'temporary' 5 months using what looked like 4mm T&E .......... thought it a bit mad, as in event of fault the very long fence would become live. |
