Line 75:
** Inside run will require either 6mm 70C cable or 4mm 90C cable for current rating.
** Isolator needs to be fitted at a suitable height to deter 'casual tampering'
** Works Needed :
*** Sort out balancing on L3 phase (see below)
*** Install 6mm 6491X conduit cable in box trunking to spare exit point adjacent West Wall
*** Use flexible conduit to bridge to a new metal junction box on West Wall.
*** Fit 4mm 3-core SWA from junction box, through wall and into IP67 rated isolator
* Traced feed for DB2A onto the L3 phase.
** This is the same phase as the downstairs workshop sockets and bandsaw
** Need to re-balance this before fitting a new 32A circuit for the heat pumps
** Sequence :
*** Remove upstairs ring main from Main Board 6L2
*** Move DB1A from Main Board 6L3 to 6L2
*** Fit 32A MCB to Main Board 3L1 for new circuit
