Great product. Easy to install. Works very well. You will need an adapter to connect it to whatever you plan to use it with. You should plan ahead if you are making your own adapter because the receptacle on the parallel unit is a CS6360 and finding a CS6361 plug for an adapter cord will probably take you a few days. My adapter consists of a CS6361 cord plug wired to a 14-50 cord receptacle using a 12 inch piece of 6-3 wire. I use it on my RV and it supplies a full 50 Amp service. I can run two 13,500BTU air conditioners, and my refrigerator with 3000 watts to spare after the compressor starts up. Very good product and the manufacturer provides incredible technical advice if you call them.
