[RE-wrenches] Recommendations for A/B battery switch

[jay]

HI Ron,

I prefer to use two ON/OFF switches rather than A/B.  That way you can always have power to the loads if you want. 

I can’t say they are the best but the Perko 9703 seems high quality and has been around for years.  Its just a single on/off rated at 450 amps continuous and UL marine.

I know this isn’t a recommended strategy and have advised him accordingly but he still insists this is a method he wants to use in his off-grid system. None of the A/B type switches I look at are really designed for regular use or that high an amp requirement. Is there a commercial product anyone has used that might do the job?
