I'\\\ve a 9.5Kw shower on a 45 amp circuit in a 100amp fuse box. The shower runs for about 1 min and then the fuse trips. It was working fine until the other day when the main fuse tripped when my misses was ironing. Changed the shower, then the fuse, then ran a 10mm cable from the fuse box direct to the shower ( just to make sure it wasn\\\'t the cable or the switch ). Did each independantly. Still trips after about 1 min. Anyone got any ideas what\\\'s wrong? I\\\'m due to move home in 10 days and in a panic!!
