Amps/Watt draw for a microwave and any heat element

[ekyyc7]

I am trying to size a battery bank for my 5th wheel.

My understanding is that anything with a heat element (ie, microwave) uses some amps purely just to start AND then more for continuous use.

Does anyone have any guides that show the average draws from heat elements for starting and running?

Thanks

I don't know.. you can look that up. They use about as much as air con, and you need at LEAST 4 big batteries.

And I don't think Mw's have a heat element.
