I would prefer to go the other way. What is a 'break before make' contactor? and how does it work?

In the link a 'breaker before make' is described. Essential as could be making smoke without one.

Thanks, I will have to figure out exactly what I need so I can build it over the holidays.

I was wondering if it is possible to just use my existing UPS backup system (designed for computers) except I would disconnect the wires going to the little UPS battery (12v) and hook them up directly to the battery in the Motormaster Eliminator.

Basically I am just utilizing a larger battery for my UPS and bypassing all the inverter & charging systems built into the Eliminator power box.

Could just go out to Cdn Tire and buy the biggest RV battery out there and hook it up in parallel to the existing UPS battery (assuming 12v) than gut the Eliminator. The only caution would be the charging circuit on the UPS could be taxed once utility resumed and if the battery was significantly discharged. Could get around it by charging the larger battery separately.

I would just try the UPS you have now on a test to see how long the battery would run the powerhead.......and if its sufficient...use it...if not...spend $100 and get a bigger one....

I already have the Eliminator, I bought it when it was on sale. I have plenty of other uses for it aside from the fish tank should I end up going another route. I was hoping I could just wire it into my UPS and save having to build a seperate relay box.

The battery in my UPS is dead, won't take a charge anymore.
