blown buss fuse/hot water heater
I have a box with two 30 amp buss fuses that sends 240v to a hot water heater. One fuse over heats and blows and now has burnt thru the wire. What`s wrong?

Check to see what the power draw is on your water heater. It should not exceed 30 amps or 6700 Watts.

If the load is over 30 amps, you would have to increase the size of the wire, as well as the circuit breaker, depending on exactly what the load is.

Thanks but if the pull is over 30 amps and it shouldn't be, is something wrong with the hot water heater? And, how would I find out what is wrong?

You need to find out the amp load on the water heater. There should be a plate with that information on it somewhere on the water heater. If the load is not over 30 amps, and it is blowing a fuse, there could be a problem with the water heater. Is the water heater old?
