Replacing a 3500 water heater element with 4500

[RuthBerry]

Hey folks. I thought both of my elements were the same so I ordered two 4500. Then my wife noticed that the panel shows 3500 for the bottom. I have a 20 amp breaker. So am I screwed? Do I need to buy a 3500 watt for the bottom or will the 4500 work? The panel is a little confusing

Both upper and lower are 4500w at 240v.

They are? So they both should be 4500?

 

[RetiredInGueydan]

Yes, as per the rating plate.

 

[Fitter30]

18.5 amp is 4500 watt
14.6 amp is 3500 watt
Code.is 80% of 20 amps =16 amps

The 3500w on the rating plate is for if you were using 208v for power. Using 240v which is most common in residential settings the elements are 4500w.

What gauge wire is run to the WH? Usually 10ga on a 30a breaker.
