I'm adding more bits to my board to mess around with and had realised that i didn't have "garage power and lighting" covered.
I understand that best practice would be a dedicated circuit from feeding property (i.e main house), connected into a garage CU with 6A for lighting and 20-32A for any socket arrangement.
When power is tapped off an exisiting ring (as my setup for this scenario hopes to be), I plan to route it first into a 2G socket (for power) then to an FCU fused down to 5A and then onward to a 1way switch.
In the back of the 1way switch i have the neutral carrying right through to the fitting and going into the neutral block (Terminal 7 if i were to use my numbering - Terminal 8 being the fixture's netural connection point)
I have the line from the FCU coming out and into COM and the Line from L1 to the light fitting (Terminal 4 if i were using my numbering - Hole 1 in LOOP block)
I've tested and the light works fine, so i got to thinking; We need the FCU to fuse down for the lights and we need a switch to turn lights on and off - Is there anything obvious as to why we can't use a SFCU (fusing down and controlling light) instead of 2 fittings (you could argue 1 fitting if in a grid system i grant you.)
I know i can mock this up and try it for myself but that won't nessecariily explain the why behind it.
If i had to guess I think it should work because the LINE feed would still be the same (into SFCU and connecting direct to ceiling rose), the neutral would still carry through, just instea of being in a wago etc, its terminated into the SFCU LOAD side.
The joys of mucking about eh? Any pointers welcomed.
