And finally, the new distribution panel, partially installed:

All circuits now in place, just waiting for a quick "tidy up" inside (forgot to snap a photo after that, sorry!):

And all finished, other than the inspection labels etc. to go on the outside:

The left-side main and MCB (16 amps) are the off-peak supply for the solitary storage heater.

The other circuits, counting from the right are:

1. 32A Water heater
2. 20A Sockets: front of store & window
3. 20A Sockets: central sales area, kitchen, side storeroom
4. 20A Sockets: counter, rear, office
5. 16A Sockets: tool display & counter
6. 10A Lights: two aisles
7. 10A Lights: third aisle, store, kitchen
8. 10A Lights: behind counter, rear area, office, W.C.

(Sorry, fellow Brits, no ring circuits employed on this job at all! [Linked Image] ).

Conductors for the final circuits are 1.5 sq. mm for lights, 2.5 & 4 sq. mm. for sockets (larger size needed in some conduits due to derating for groups), and 4 sq. mm for the water heater.
