The above appliance surge and rated watts are based upon industry standard assumptions. Your appliance and tool power requirements may differ. Use the Reliance THP103 AmWatt load meter to measure what your appliances specifically will require.
Surge Watts – Watts required to start the electric motors in your appliances or tools. Please note that the power required at start up has been known to be 3 to 5 times that of rated or continuous wattage to maintain the operation of the tool or appliance you are running.
Rated Watts – Watts required for continuing operation of the tools and appliances you are running from the power supplies by your generator.
