I have a old type fuse box running to my water heater, the heater is a 2 yr old 40 gallon, the fuse box takes 2 old type fuses, not the screw in, i was useing buss one time non-20 amp fuses,they would blow sometimes about once a year or every 2 years, tonite one 20 amp fuse blew and I mean BLEW!, fire, sparks all coming from the fuse, It happened 5 mins after I took a shower, could it be a major fuse failure or is it the box, the wires look okay, I'm going to put in a breaker box but I need to find some one to wire it up first. the fuse that blew was put in there about 2 years ago. I am terrified to try and put another fuse in there out of fear of burning down my house
I'm not exaggerating, when the fuse went it was like the 4th of july, the burnt smell linger even thiugh its been 8 hours now, the wire is #10, AllanJ I have 8 fuses I can use all are 20 amp .
