How many amps does a 40 gallon water heater pull?
So a 16 amp heater should be wired and protected by a 20amp circuit or a 20 amp breaker should only feed a max of 16 amp load. Bottom line, For a 4500w heater w/240v it will draw 4500/240 or 18.75 amps so #10 wire and either 25 or 30 amp breaker, depending on code.Click…

A water heater of this type is required to be considered a continuous load meaning that the branch circuit needs to be calculated at 125% of the heater’s rated ampacity. 4500/240 = 18.75 amps, will work on a 20 amp OCPD but, 18.75*125% = 23.4 amps, requires a 25 or 30 amp circuit.How many watts does a 40 gallon water heater use?
