hi mudhoney, have you tried renewing the isolator swich as if it has gone down it might be your problem, i take it you have an r.c.d. fitted to your main board if for any reason you have a leak from the nuetral to earth bingo out she pops, you might have a bad fault with the isolator swich, or by operating the boiler as soon as power is returned via the nuetral it may be leaking to earth in the switch either way the r.c.d.would trip. tobjakjerry
