Review on 🚀 Power Up Your RV or Boat with Nilight 90101E: 5 Gang Rocker Dual USB Charger, Digital Voltmeter & 12V Outlet Pre-Wired Switch Panel with Circuit Breakers - 2 Years Warranty by Issac Burnett

Product as I expected, well built and will serve my camper well. but I didn't appreciate it until I got it as it is prewired. Each of the 5 switches connected in parallel has a common power supply. Each switch output contains a 15A fuse. The problem is that the 16AWG AWM cable, including the common supply, is only rated for 8A, so the total load of all 5 circuits should not exceed that rating. The common power wire must be a large size 8 AWG (40A). In my case this is not a problem as I use intermediate relays (Rayex LD1A-12F-R) for all 12V DC loads in my system. The coil load (from the Nilight switch) is only 150mA but the contacts are rated for 40 amps which is more than enough for a water pump, stove etc. I also have a 120VAC and AC water heater, this is what I use a TWTADE SSR-40 DA solid state relay that switches with only 10mA. For any other practical use, remove the common power cord and route the individual circuits through switches. Make a few for some things, nothing special. One bizarre observation is that switches go into the "energized/on" state (but sailors are an odd bunch).
