long flex for boiler thermostat under floors

[jeremy]

Are you terminating said flex? if it's the plumber, remind him to terminate the ends properly, and use blue and brown sleeving for the neutral and switched live!

Make sure your EIC excludes the wiring done by the plumber/boiler man

No as tel said even cables supplying equipment that doesn't require a earth should have a cpc helps with the whole ADS thing when someone nails through it

I've recently had this very same argument with my builder mate who wanted to use 2 core flex to wire 20 downlights in his kitchen ceiling.

The use by plumbers of 4 core flex and over-sleeving the cpc in any colour, gets my goat (and, remember, I'm a newb at this).

Do plumbers, chippies etc. not have OSG's to help them do a neat and tidy (compliant) job or just anything goes? Is it just sparkies who get all the carp thrown at them?

[Minor Rant] My old man was a self (?) trained plumber. He could fit copper pipe work under floors through holes in the joists no bother. So what's the crack with modern plumbers? [/Minor Rant]
