    This is working great for us. Only 8 circuits but if you choose them carefully, everuything essential is covered. We have had several power outages in the last two years and this makes us functional at a very lower price than getting a whole-house generator.

    Control &amp; Power Cables

    Posted by Joel Nuss on 9th Nov 2020

    The design for the attachment of Power cables is poor. The main power output cable needs to pass through the removable access panel in the rear. This makes the attachment of this cabling, at best, awkward. The output cabling should have been routed through the SIDE where the Control Cable is routed.
