Single 50A vs dual30A (60A) breaker
Final chapter on my Kohler 6.5CZ genset. Looks like the previous owner removed the dual 30A=60A circuit breaker and replaced with a single 50A breaker. I found the proper breaker and was ready to install. Now remember I have NO ID plate on this baby to reference with confidence the spec version. So now I have both LINE leads from the gen head going to a single post on the breaker, and both load wires sistered up on the line side. The neutrals and grounds are set fastened to a single post on the unit. in this diagram, there is mention of a jumper wire from the line leads in some instances. However, there is also a scenario of NO jumper also. A bit confused as to how to proceed. In regular wiring it looks like a 220V system as the neutrals and grounds are sistered together. This denotes a 220V system. How can I determine this? Place a meter with one probe on the line side and one lead at the ground?

Re: Single 50A vs dual30A (60A) breaker
OK, just placed a meter on between the sistered up line leads (photo 3) and the sistered up neutral/ground leads (photo 4). I am getting 123V on my meter. SO I am assuming it is a 120V system and requires the jumper as per in the wiring diagram?
