UPS Manual Bypass

Dave mcn 1 month ago

Hi everyone

I have a customer that wants a manual bypass for their UPS

Currently there is nothing, the feed goes straight through the UPS and to a sprinkler pump via a control panel.

They have confirmed that they just want it for manually switching over to mains supply if the UPS fails.

The circuit isn't critical and can be interrupted to switch over to mains.

Their budget is tight as they are a charity.

I am thinking of just using a 3 position changeover switch.

Any thoughts please?

There are change-over switches that don't have a centre-off position - e.g. https://www.tlc-direct.co.uk/Products/CGM125CS.html (I presume they're still break-before-make, but double check).
