Reverse polarity is not good for flat screen TVs and AC but you can still use a toaster, fridge and charge the batterys.
You're not dead. You just plug into the front outlet that bypasses the surge unit.
Buried under a cabinet? How hard is it to open a door?
I guess that's why they make both built in or portable so you can make a choice.
I thought this thread was about water pumps.
