Seeking confirmation as to correct or 'normal' connection method for an electric towel rail (around 500W) on a bathroom wall (which is well away from the bath).
What I envisage is:
1 Spur from ring mains (RCD protected circuit) socket nearby outside bathroom. to
2 Fused switch on wall outside bathroom wall with a neon indicator to
3 Unswitched spur connection unit with neon indicator near towel rail (final connection by flying lead)
Intermediate cabling (1 mm^2 or 1.5mm^2) to be buried in chasing under plaster.
Am doubtful about the cable spec from the ring connection to the first fused switch. Should it be in 2.5mm^2 cable?
Any comments most appreciated.
TIA
