I'm installing a cooktop in a kitchen island. The appliance requires a 50A 220V breaker. The appliance has a green/ground and two hots/red&black. The instruction manual shows two ways to wire it:

1) Supply two hots and a neutral. Ground neutral & green from appliance to the electrical box. Connect hots.

2) Supply two hots, neutral, & ground. Ground ground & green from appliance to electrical box. Connect hots. And for some reason the white/neutral gets capped off.


Any reason not to do # 1???


Thanks,

Mike
