Hi guys,
my boss owns a small sandwich shop thats been plagued by rodents running under the floors from neighbouring properties - and stopping off (drive-thru style) to nibble at the cabling for the premises. Unsurprisingly causing loads of problems.
It now needs most of the circuits redone, either due to damage or due to not being sufficient for current usage - and extension leads running all over. He's asked for some ideas on circuit layouts + loading. He wants me to do it while quiet.
Hes planning on using a split load board 12way wylex. The current one is a 8 way volex or other tat with various makes/ratings/curve mcb's.
There are a few high power items, one lighting circuit, and the rest would be ring circuits for sockets. One idea i'd mentioned to him would be to try keep fridges/freezers somewhat seperate from the rings, to avoid poss tripping via rcd, but how separate do you go?
Having thought about the bits, i was thinking of sugesting :
1 Light circuit could be split into 2 if req'd but 6a mcb is OK
2 Dishwasher circuit, radial 2.5mm 20A mcb
3 Coffe maker circuit, radial 2.5mm 20A mcb
4 Fridge circuit (1x domestic fridge, 2x domestic chest freezers, 1 commercial fridge), Ring circuit 32A mcb
5 Future/proposed Grill circuit, radial 6.0mm 40A mcb
6 Seating area sockets, Ring circuit 2.5m 32A mcb
7 Front kitchen area sockets, ring circuit 2.5mm 32A mcb
8. Back Kitchen area sockets, ring circuit 2.5mm 32A mcb
9 A/C unit, radial 2.5mm, 16A mcb
Would this be worthwhile or should some of the frisges/freezers be split onto 2 circuits? There are 2 more drinks coolers/chiller units but they aren't as important so prob just go onto normal kitchen ring socket.
What would you suggest to be RCD/non RCD protected?
Thanks for any ideas!
