I hope someone can shed light on what may be a problem here - it's got me very confused.
Renovating bathroom - removed (working) wall fan heater fed by FCU outside bathroom (bathroom is next to kitchen - FCU is in the kitchen, load feed wire through wall directly into appliance). The FCU is supplied as a (junction box) spur from the ring main.
I have removed the fan heater and installed an electric towel rail. However, when I connect up the towel rail to the FCU it won't work. I have tested the towel rail by means of fitting a 13A plug and it's definitely working. The FCU supply live tests live, as does the load live when you switch the FCU on without the towel rail connected. However, once the towel rail is connected and you switch the FCU, both the supply and load lives disappear?? Have changed the FCU - same problem.
Am I doing something very wrong? Grateful for any advice - the towel rail is certainly <13A.
