I have a GE50M06AAG water heater and likely need to replace my elements. I've read the manual and looked on the tag on the water heater itself but am a bit confused as to which elements I need to buy at Home Depot.

Here's a picture of the tag:

I noticed that the UPPER/LOWER says "4500/3380" but wasn't sure if that meant use a dual watt element or I could use only use a 4500 watt element at 240 volts and a 3380 on 208 volts?
