Cable calculations help

[kirkbykarl]

Hi I'm at an installation which is a servery counter. It has a 8way 3 phase distribution board protected by a 63A 30mA R.C.D the circuits are wired in 1.5mm 3core flex and are protected by 16A 60898 MCB's (all radials). They supply socket outlets which allow appliances to be plugged in.

My my concern is are the cables sufficient for the circuits? Bearing in mind the appliances are all under 13A the cables are bunched in groups of fours and fives and clipped direct.

any help on this would be greatly appriciated

thanks

calculate themax. current Izfor the cables allowing for derating where necessary. as long as Iz>In>Ib then it's OK.

I'm old fashioned I guess sockets wired in 3 core flex? not for me, tin hat on, stab vest on ready for all the flak

agree, pete. but as long as cable CCC and VD are within parameters, he can't fail it.

Catering equipment is often in heat resistant flex. You try and reconcile it with M&Q regulations. It gave me a headache.
