for an electric water heater in a home , are there any rules or suggestions on the height of a water heater disconnect switch, in a garage
Over 48inches like all the recepts, unless in a flood zone. Then match recept height. If within direct line of sight to the breaker/panel a disconnect is not required by code. I would just put it about “face” (where you are looking directly at disc. at eye level) height. Hope this helps.
