Question about Coleman Powermate Premium Plus 6250W Portable Generator
My 5kw Coleman Powermate generator has two 110v receptacles and two 220v receptacles. Both of the 220v receptacles are the 3-prong blade type. My six circuit Reliance ProTran transfer switch has the 4 prong female twist lock. Both ends of my 30amp 4-wire cord are twist lock. The end for the transfer switch is no problem. My Coleman manual states if I am going to use the 220v receptacle to power up any 110 circuits, I have to use the transfer switch, which I intend on doing. It also says I have to have an adapter plug inserted into one of the 110v receptacles. Something I didn't understand about floating and bonded grounds. It says the ground and neutral terminal on the adapter plug has to have a jumper wire connecting the two together.
I was going to buy a three blade male plug that fits the configuration of the 220v receptacle on the generator. I thought I could cut off the male end of the 30amp twist lock power cord and hook the wires up to the new plug. My plan was to just connect the white neutral wire and the ground together on the new plug. Will this be the same thing as making an adapter plug and pluging into one of the 110v circuits? Will it work? Any other alternatives? Thanks, Steve
That is a bad idea use the transfer switch even if you have to hire someone to hook it up right. the cost of messing up is way more. and hard wiring is illegal and can get someone killed. around here pull a seal on a meter and they will fine you big time.

Hey steve. do you really need 240 volts for 120 v. circuits. the reason you have to have an adaptor plug is because on your 220 volt plug in , 2 of tthose prongs are hot and 1 is ground. for safety you need to get a plug adapter ( a regular 120 volt plug end ) run a ground from adapter to ground on 220 adapter. same with nuetral. you also need to ground your generator. there is usaully a ground lug on the bottom of the gen. Another way. if you dont really need 220 v. is to use both 120v. recepticals on gen. Run 2 chords to tranf. switch. and hard wire it in to switch. another way i did mine . when i lost power in this hurricane. i ran two # 10 chords from my 2 120v. recept on my gen to my breaker panel. when you do this you have to pull the service meter, if you dont when power comes back on it would backfeed through your gen.then i turn all my 220v. breakers i was able to run lights ,ciling fans, freezer, ice box,washing machine and gas dryer , tv's computors etc. . but to do this, you probably need someone that knows what they are doin.
