Urgent 3 phase supply in kitchen

[gary8407]

Hi im just looking for a bit of advice, im helping install a 3phase deep fat fryer in a kitchen, the BOSS says a 6mm swa will be fine, ive looked at the info from the manufacturer and it says L1 = 31.7A L2 = 31.7A L3 = 17A.

In the regs book a 6mm swa can take 42A, im just wondering, is that per phase or in total?

Any help or advice would be appreciated

Thanks

per phase depending on the install method

i would guess the line currents should be nearly equal for a 3P fryer however

Not according to the OP the manufacturers current per phase are not equal

i would have expected 3 identical elements in the fryer

could be wrong though

L3 load been mis-keyed perhaps

Could be that it is a 3 basket fryer with 2 full baskets & 1 half basket with each section of the fryer in effect being single phase.

No it will be a 3ph and neut and l3 normally only does the ancillary circuits it's the same with the big 100amp rationals

there's some lincats' here- line currents are identical
