A lot of people have been able to energy their home with a generator by branch off a categorical breaker as well as afterwards plugging their portable generator by a 240V dryer connection. However, my Honda EU3000is usually has 2 110V 20amp connectors or 1 125V 30am lockable plug. Is there a approach we can bond this to a dryer tie (or any alternative residence connection) but a send switch? Electric companies have been wanting to assign in between 00 to 00 only to implement a foolish send switch. we need a cheaper resolution

You are playing with fire in your attempts to improvise a solution. What you are suggesting can not be done in an approved and safe manner.
Do not back feed the panel in your house. You can use extension cords to power selected devices if required. Otherwise the only safe and approved technique is with a proper transfer panel.
Read through my generator pages for more information.

David’s response is simply irresponsible. Read his last sentence if you need more justification! I’ve added his pictures to my bad installation pictures…

you need,a length of 12/2 with ground, and 2 male plugs for the generator ,and a dryer plug ,install both plugs on 2 lengths of wire enough to reach the dryer plug(the shorter the better). then the other end of the 2 wires a black wire on the right and left of the dryer plug and both white twisted together for the common and ground if available. be sure to hook the 120vac plugs with the correct polarity ,the black on both must be the hot,and white common.

I have the same generator and had the same dilemma. Here’s what I did.
You need a 30A breaker, a male extension cord terminal, a female extension cord terminal, and about 2 feet of 12/2 Romex. Don’t expect to power your entire house. Find a couple of circuits that you need, and make sure they’re on the same bus. All I needed was the fridge, microwave, tv, and a lighting circuit. Shut off the main breaker. Attach the 30A breaker to the bus with your desired circuits. Properly connect your romex to the male plug, then to the 30A breaker, ground and neutral buses. Use the unwired female plug to insulate the male plug when not in use. Now put clear instructions next to the panel and make sure they are followed to the letter!
1) Shut OFF main power supply
2) Shut OFF all breakers in panel
3) Connect generator to panel with shortest possible 12 ga wire extension cord.
4) Start generator and allow to run 5 minutes to warm up
5) Check again that Main is OFF
6) Turn ON 30A breaker
7) Turn ON required breakers
If the generator is connected with the main supply on, you run the risk of electrocuting utility workers, and being charged with manslaughter.

Of course, even if I said put a lock on the main breaker to keep anyone from turning it on, the electricians would bitch about it. They need their $135/hour.

Safety First! You have a generator that produces 120V, not one that produces 240/120 volts with a common neutral and there is no way to externally change this. You can run extension cords OK but the idea of back feeding through a branch circuit is not smart. There is the possiblility that one of the 240 (2 pole) breakers could get turned on and the appliance (like a waterheater) would then cross feed back to the other side of your panel. There is also the VERY serious issue that there is no guarantee that the main breaker is turned off. This is a electrical code issue that is there to protect utility linemen from being killed. You would need to install a transfer switch between your panel and the utility or an interlock kit that keeps the main breaker and the back fed breaker from being turned on at the same time. The kits are pretty cheap for the safety you get. Check your local electrical supply house or http://www.interlcokkit.com if you decide to go forward and buy a generator with the required output.

I would like to connect my coleman 6250 watts to my panel box without running a seperate panel. My only delema is the 240 volt plug does not have a neutral wire. So can i run my 110v through an existing plug and will it supply what i need it to?
