Which way should it be wired?

You need to wire(jump) L1 and L2 together. If you do NOT, then your transfer switch will not work and if no transfer switch only 1/2 of the 120 breaker panel will have power. I have this type cord in our shop for ease of moving the cords and have built one that is 50 feet long which is cheaper than using a 50 foot long 4 wire 50 amp cable. We use them just to get quick 120 power to a 50 amp coach when we do not need more than 30 amps of power. Doug

My coach is wired for 50 amps, but I also did not like the heavy cord. But in my case, I replaced the heavy cord with a lighter 4 wire cord as both of my circuits are limited to 30 amps each at the coach and I can never draw an actual 50 amps. It made my life easier!!!
