   I recently upgrade my emergency generator from a 9000 watt unit to a 13000 watt tri-fuel generator. This meant I need to upgrade from the 30amp connector and cable to 50amp units. These is well made and was easy to install. It is rated up to 12500 watts which is under my generators rating but that is max starting load running on gasoline. I have this generator connected to natural gas so it is rated below that and gives me plenty of leeway.

   This setup is advertised as a 50A wire to connect from a large generator or shore power to an inlet box with a SS2-50 receptacle. This looks and feels like a very nicely made cable and also feels very heavy duty. My issue with it is the AWG of the cable itself. Its made with 8AWG cable. This size wire is designed for only 40A not the advertised 50A. Having said that, pulling a constant 50A is not something that you would do on a regular basis. However, if you need to pull 50A you need to use a 6AWG wire (which is rated for 55A). The inlet box seems good. The metal frame has a nice coating on it that should allow it to resist corrosion. The design also has sides that overlap which would keep water from intruding. I did notice that the box isn’t very deep. Its VERY difficult to fit wires into that outlet; there just isn’t a lot of room in there. I also wish that the receptacle was angled at a downward slope. This would provide some strain relief on the cable. Since the cable weighs a lot, gravity is pulling down on it pretty hard. The Cable itself is constructed very well. The outer sheath is tough and resists damage. Its really thick so its challenging to maneuver. As stated above, it should rally be 6AWG if you want to pull a constant 50A but in most use cases you wont have a constant heavy draw for hours at a time (unless you are doing EV charging). The adapter to connect to a 30A plug on a generator is solid. Its really heavy and holds the prongs tightly. Overall, Im satisfied with this cable. And since I don’t see myself and running this a 100% capacity, im sure the thinner cable will suffice.

   I know that this should have come with 6 awg wire, but it did not. With that said, unless you have a 9600 watt or higher generator, you will not have any problems with this unit. When you install it to the panel, you should make sure that you use a 40 amp breaker just to make sure that you don’t have a problems with drawing more continuous for long periods of time than the cord can handle. Since I’m using this with a much lower power generator, just for an easy way to get power to my refrigerator and some lights this was a good solution for me. If I get a larger generator down the road, I can always buy the right size cable.

   With that said, electrical can be dangerous and it is always planned for some margin and worst case scenarios. There is good reason for this and you should make sure that you put some failsafes in for worst case situations. Also, if you’re doing this yourself, which nobody recommends, please make sure to use a interlock to make sure that you can’t have power from the the utility, and power from the generator at the same time it’s not good for your electronics and it’s not good for lineman.

   Very thick and heavy duty extension. It protects from the heat, water and it says even rust. It is extremely long. Works very well with my generator.
