Review on ATPWONZ Waterproof Electrical Underground Connectors by Kevin Bucher

These boxes are fantastic. I use them on 120 volts AC and they work great. I urge anyone using them for AC transmission to be confident and make a load chart with real world calculations. For example, I have a circuit with two LED lights and a ceiling fan with LED lights, and there is almost no heat on the box. (According to my thermal imager) That's about 60-70 watts with the fan on. I drilled a hole in the back of the case and used a grommet screw to secure it under the deck, then added some silicone for the cable entry and screw. I also suggest never using a fork in a circuit with this connection. You just don't want anyone plugging a stove or toaster into it. The included internal cable connectors are made of "lightweight" rather than heavy plastic, similar to that found in an electronic device power supply. Let's say 1200 watts of continuous use with a 14 GA power cord is no problem. (just a guess)
