Thanks for the comments. :)

Understand, a while back Ford had a recall on pickups. The stop light=20
circuit was protected by say a 10 amp fuse, and went from the stop light=20
switch on to the cruise control in addition to the vehicle and trailer=20
stop lights. The free TSB was to add a low amperage fuse at the switch.

For circuit protection, I was thinking of either a pigtail fuse, say 1/2=20
amp, or a piece of wire wrap (30 ga. ??) as a fusible link. With the few=20
components, I wasn't thinking of a PCB, but jut twist and solder leads=20
together, then pot the whole thing in a block of  epoxy. The location is=20
on the hot water heater access panels for changing a heating element.=20
There is a little concern, the tank insulation is foam, don't know how=20
flammable, but going to conservatively assume it is.

Since the electric tank is backup to our gas well fed natural gas tank,=20
it is rarely used, but would like an indication if it is inadvertently=20
left on, generating a high electric bill.

Any comments appreciated.
