Discuss can two 6mm csa cables each with 30A mcb in joined at 50A dps to supply 9.5kW shower in the UK Electrical Forum area at ElectriciansForums.net
perfectly OK till the insulation monkeys smother the cable.
But the (40A) current is shared down two 6mm cables (approx 20A down each). And each 6mm cable has its own 30A mcb back in the CU. From the 50A isolator pull switch near shower, where they join, the single cable to the shower is then 10mm. I cant see any over loading / overheating at all. Am I still missing something here.
Except for failure to comply with regulations why would this not be safe?
Any advice really appreciated
Thanks

This thread is the classic example of how Dan needs to change the forum. If the OP is unwilling to attempt to answer some of the questions he should be put on a ban until he does.
Thanks to you who have replied genuinely to my question, without feeling the need to result to sarcasm. No I am not a qualified electrician and never claimed to be but I am both a physics graduate and electronics engineer. I never doubted that regs would not allow this to be done, though from an electrical theory perspective it is perfectly feasible, Its a shame very few replies seemed to go beyond 'you cant do it as it breaks the regs' and considered the theoretical reasons why...of which there are few.
Thanks again
