Thanks for the intro Bill - Our panel model 2206 is a slick panel giving you 12 circuit breaker positions (you choose the amperages), a main, a meter and a switch that can be wired to perform a number of actions. We have sucessfully designed an AC Digital Multimeter but are only in design stages of a DC Digital Multimeter which would've been ideal for this panel and application. I would like to see the pictures and actual measurements of the Lorco panel to see what we are working with and get the J/30 owners an accurate drop-in panel replacement. Please pass this information along at your convenience.
