[RE-wrenches] Stacking SW Series

[Ray Walters]

I never liked the original SW5548. It had different firmware and 
actually can't surge as much as an SW4048. The 5548 does have a very 
heavy transformer, so they would be good for a heavy continuous load 
that didn't surge much on startup.  They're hard to put up on a wall.

I don't know anything about the SW+, I had switched to Outback back 
then.    Did you read in the SW+ manual that it could be stacked with 
the SW?  Unless they designed that into it, I'm guessing they wouldn't 
stack.
