Trying to change my lower water heater element. Label reads 3380 for both upper and also lower element. Went to go uncover a replacement and also only saw 3500W and also 4500W. I"m leaning in the direction of 4500W...read around the net and also saw that it relates to 3380W, through the voltage 240/208V. Also, review that it have to be close in wattage...3380W and also 3500W to not blow the fuse. Please let me recognize if I"m thinking about this correctly and also should be acquiring the 4500W water heating element. Thanks!

Not a electrician yet from my understanding as lengthy as the breaker is 30 amp and also a particular gauge wire, i think #10 indigenous what ns read, it have to be OK.The higher watt draws more amps. And also most water heaters have only one aspect on at a time.You will draw like 20 amps for a 4500 and around 15 amps for the 3500.Wait for the electricians come come on and verify.High voltage in there. If DIY and also are no sure just how to job-related with 220v higher a pro. Likewise IMO if the water heater is larger it may be more cost effective to replace the heater.Mike NJ

What gauge wire is run to the water heater and also what size breaker or fuse is used? If it"s a 20 amp circuit, you cannot arbitrarily boost wattage to 4500 without installing a brand-new 30 amp circuit.

There are couple items it will certainly arise v this one the 3380 watts is offered with 208 volt network system so if you have actually 208 volts supply climate the wattage will certainly be correct yet if you have actually 240 volt actual it is provided the wattage will certainly go as much as 4500 watt due you have the right to NOT win the ohm"s law. The factor why due part circuit are limited to 20 amp so as such you only have the right to use max of 3840 watts this is on 80% that 20 amp 240 volt circuit The 208v circuit will certainly be reduced yet 3500 watt at 240 volts is best on par top top 20 amp circuit but once you past the 3500 watt rating there space two thing will change the whole thing is friend will have actually to lug out 30 amp circuit for this purpose and if water heater rating execute say 4500 watts max then you are ok top top 240 volt circuit. So the why I simply want to offer you a head up with it and additionally be mindful there are couple of diffrent style of heating aspects majorty of them will be screw on type but some space standard element and also some are low density element that is offered with hard water locations and some that water heater will have actually 4 bolts to organize the key in those usaeally uncovered in older water heaters last thing prior to you ever drainpipe the water make certain you revolve off the power before you drain or open up the cover and also one last reminer Jamias never ever rotate the strength on till the water heater tank is yes, really full very first otherwise you may burn out the new element.
