Looking for the best solution on a damage limitation rewire...

Two bedroom semi with a 10.5kw shower in bathroom upstairs wired to a 45a p.c in 10.0mm t&e. There is no way of getting to shower unless the wall is chased out in bathroom or hallway. Problem is client does not want her bathroom damaged or hallway damaged and insists on no trunking. The existing switch wire is run in 6.0mm t&e.

Any ideas?

Wording Is pretty crap, on my mobile.

There is a 10.0mm coming from DB to pull cord and an existing 6.0 switch wire going to shower. Trying to find a solution to re wire the switch wire without any damage.

Totally agree, only option given the circs and wil cost a lot less then redecorating, and besides how hot do you want your shower? lol​

beats me how these customers buy these ridiculous high power showers, then think we can magic them to work without installing cable. iv'e just installed a 8.5kW mira , partly because i refuse to attempt to force 2 10mm cables into a pull switch designed for max. 6mm. on full heat it's scalding. why on earth go for 10.5kW?????

I have a 10.5kw to fit, and upgrade of cable to 10mm. I think the reason is not for total heat output, but the heat to pressure ratio. The 10.5kw shower can heat the water up to a good temperature without having to reduce the flow to a prostate cancer restricted urine flow amount.

DOH... always thought the purpose of a shower was to get clean, not to drown under a torrent of scalding water.

If you lived in sunny East Anglia you would understand the need with the farty water pressure we get round here!

If you know how the shower is wired from the switch in 6mm cable then it could be possible. If the cable is clipped direct then as Table 4D1A states the cable is rated at 47 amps. It should be realised that the shower does not run flat out all the time only when it is heating at max.

All ways do the job correctly,you will have to run new 10mm from switch then down to shower in trunking or by removing a few tiles,or she gets a lower rated shower,if not you will have to walk away
