Discuss Shower Cable in the UK Electrical Forum area at ElectriciansForums.net
BS7671 specifically permits paralleling cables, with certain provisos on cable route, type, etc. to ensure equal current sharing.I'd be interested to know if there's actually a reg that forbids it in the UK, I know there isn't in our domestic regs. As said already, it's common practice with cables in larger distribution networks but the logistics of ensuring identical lengths, routes and connecting a parallel cabled domestic final circuit would make it a bad idea.
I think id be more concerned about one of them being disconnected then overloading the remain one.
You will not need to worry in another few years because of the EU the power of vacuum cleaners are being restricted next they are going to restrict our power tools so soon your showers will be a maximum of 3KW and you will have a fine mist spray to that you reduce your need for so much water and then to round it off your bath towels will be the size of face cloths ! pmsl
As long as the two pull cords are tied together to ensure isolation of both at the same time.Cant see why the op doesn't go for 2 x 8Kw showers side by side with a 6mm T&E for each, LOL....
How would you test it? As a radial or a ring final circuit?
I'm not sure the resistances in parallel are such a good idea either.
Might be a good idea to check the fire insurance.
And not 1 person as mentioned the common practice of connecting 2 x 2.5mm cables 2 a 32A breaker !!
Sound familiar !!! :icon12:
Yea but! no but! yea but!
You have a point athough as mention we would not consider parrallel cables in a domestic installation It just sounds crazy to do this but technicaly speakng surly a ring final circuit is in affect a parrallel circuit from a certain point a view :shades_smile:And not 1 person as mentioned the common practice of connecting 2 x 2.5mm cables 2 a 32A breaker !!

Yes i know that but ok you have 1 twin 13amp socket fed by 2 x 2.5mm cables on a 32 amp rcbo both cables run the same rout so is that a radial or a ring
final ?
