Electric booster water heaters are available for operation on standard power systems. Check the nameplate for the proper power supply.
All internal electrical connections have been made at the factory. See Circuit Breaker and Fuse Sizing Chart for supply wire size, fuse, breaker and conduit recommendations.
WARNING !!
For proper electrical installation conforming to local electrical codes, consult a licensed electrical contractor.
WARNING !!
The main power circuit must be disconnected prior to performing any maintenance on the booster heater to avoid possible personal injury or damage to the heater.

Temperature/pressure protective equipment should not be less than a
combination temperature/pressure relief valve certified by a nationally
recognized testing laboratory that maintains periodic inspection of the
production of this equipment and meets the requirements for Relief
Valves and Automatic Shutoff Devices for Hot Water Supply Systems,
ANSI
must be marked with a minimum set pressure not to exceed the marked
hydrostatic test pressure of the booster heater.
