How many homeowners are going to pull a new wire to install their new night-light switch that the guy at Lowes sold them?

I know you can't predict every dangerous thing someone might try, but I can see where it's coming from.
you good!

I have two sump pumps in my pit both are 120v pumps and the way I would like it set up is one is the primary pump and the other is the secondary. the secondary has the capability to take over if the primary should fail. but my only problem is I have no battery back up pump that would run off 12v dc. what I would like to do is use the secondary pump as the battery back up (by the use of an inverter) in the event of a power outage. my biggest challenge is finding a relay that can switch between the main 120v and the inverter 120v? any recommendations? I know this isn't the right forum figured I had the best chance getting looked at

If you really want to go that route then search for inverter charger. It will switch from mains to battery when the mains is down and will use mains power as a pass through (and to charge battery) when it's up. They're typically expensive, and not the route most would go for a sump backup setup. There's an inherent loss in the conversion from DC to AC through the inverter. That's why the backup sumps are typically DC. No conversion loss.

I'd also recommend starting your own thread next time as your question has nothing to do with this thread
