Industrial Cooker Cable Size

[Jon Bridges]

Installing a 3 phase cooker with 6kw on one phase, 6kw on the second and 3.5kw on the third. The instructions recommend using flex. In BS7671 I'm using Table 4F1A, page 292 and therefore need 6mm flex. This sounds a lot for 26.1 amps on each phase. Am I being dumb?

Also can anyone recommend an isolation unit for the kitchen

63 amp rotary isolator , then a length of 6 mm 5 core SY flex , cable ,glands etc , the reason i chose the 63 isolator is there is more room for the cables when using 5 cores the 32 amp one can be very tight

Great shout on the SY flex. Never used it before, it says on TLC it is ideal for food preparation

great for the job tough and very hard wearing and available in all sizes relatively cost effective to
