I've been having problems with a gas water heater and am considering going to an electric model.
My question is, how do I tell the amp rating of the fuse box? If I'm going to need to install a bigger power handling box that'll figure into the costs.
There is plenty of room for the fuses, also, when I moved in I installed a larger A/C unit. While at it, I thought the existing wires, 12ga, would be too small so I ran another bigger set of wires for the new A/C Unit, 10ga. The old wires are just tucked out of the way (all appliances are on the same side of the house so I would just need to re-run the old conduit over to the heater location) so I could use them for the electric water heater. But, I don't want to over tax the electrical box.
Thanks in advance for any help.
