what's wrong with 9.5kW on 6mm 40A as long as it's ref. method C?
What is 'ref. method C'? as I thought anything above 7.5kw needed to be on a 10mm feed? and 40A on a 6mm wouldn't the cable be burning out before the MCB trips? not trying to be clever just want to learn or was your post sarcasm or something lol[/QUOTE]
Tel sarcastic ? no not at all he doesn't know the meaning of such traits(thats one beer for one lie Tel)
The figures he suggested are indeed bordering on the reality of cable selection
time to pick up some books methinks...What is 'ref. method C'? as I thought anything above 7.5kw needed to be on a 10mm feed? and 40A on a 6mm wouldn't the cable be burning out before the MCB trips? not trying to be clever just want to learn or was your post sarcasm or something lol
Interesting issue and I dont know the answer so someone of higher knowledge than me please explain the rationale.
Original shower fitted without RCD protection (assume correctly to regs at that time) and identical shower now fitted to replace 'old' shower on a "like-for-like" basis (assuming they can still be sourced) but manuf instructions for the exact model now require an RCD whereas it didn't before (again assuming RCD's were being used then).
Can you claim replacement on a "like-for-like" basis as the current regs allow (and as instatallation was totally acceptable by the manufacturer originally for that model) or do you need to upgrade to current stds as if fitting new per manufaturers instructions? (i.e RCD protection).
Set aside that we all know that RCD protection is ideally the correct way forward for virtually anything that is fitted in the home, what is the actual position of what can or cannot be fitted to meet the regulations retrospectively?
Sorry if this is too deep an issue to be discussing on a Saturday night but as Im stuck at home baby-sitting I though I'd throw it in the pot to stop the rest of you lot going out and enjoying yourselves whilst Im remaining sober!!
Ahhh that big green book, I have one of them in my college bag I'll pay more attention to cable ccc's next time.
iam going too fit an rcd and told the costumer that but i didnt want to tell them it has to have and rcd to comply with current regs and then they google it or ask another spark and they say it doesnt , its that type of customer
