Re: [RE-wrenches] Manual Two Way (Bypass) DC Transfer Switch

2012-04-25 Thread Christopher Warfel
David Click provided a document from Outback that describes the way this 
concept works, making my need for the dc transfer switches unnecessary. 
Thanks David, hats off.

are operated in proper sequence, but I thought a bypass switch would 
be more fool proof or safer for the owner.  Thanks for any leads.  Chris
