UPDATED POST ... didn't edit last entry before thread closed ... trapped foot in door! ;-))
Looking closely at the photograph ... I see 11 wires entering from above and 6 from below.
From above, LtoR at exit from conduit:
- 1 x Brown: Feed to bottom of LH switch; brown from top of LH switch feeds common terminal of timeclock
- 2 x Grey
- 1 x Blue
- 1 x Red (orange tinge): Line feed to top of MCB
- 1 x Black
- 2 x White: Straight through box?
- 2 x Blue: Front, neutral, wire feed to top of MCB; rear, neutral, goes straight through box
- 1 x Green and Yellow - CPC?
From below, LtoR at cable tie:
- 1 x White: Straight through box?
- 1 x Black: Switched line from MCB
- 1 x Green and Yellow: Straight through box - CPC?
- 1 x Blue: Switched neutral from MCB
- 1 x White: Straight through box?
- 1 x Blue: Smaller, neutral, straight through box
Does RH switch do anything? Switch MCB switched line or one of white wires?
Melee of black, line or switched line wires, above the timeclock prevents identification of whence they came or go to; further details of 'live' side of circuit need to be identified.
Likewise blue, neutral wires; source or destination of each is required, of particular interest is the loop of blue wire below the LH switch and LH side of the timeclock.
