Using Generator As Backup For House Power
Eric, a few years ago, I ran a few extension cords from my coach to power
the furnace, refer, lites and tv. I did not attempt to attach any of these into the breaker panel- as that is as far as my electrical expertise would allow. Ice is melting as we type!!! Ernie Ekberg 83PT40 Weatherford, tx [Non-text portions of this message have been removed] |

Using Generator As Backup For House Power
Ice storms may bring loss of power to our home as in other areas of the country
so I brought the coach to the house with the idea of moving into it if we have a problem. Then I got to thinking about using the generator to provide power to the home so we could have heat and lights. Has anyone else done this? What would be the best way to make the connection so you get maximum use of the generator capacity? Regards, Eric in San Antonio 84FC35SBWL2 |

Eric:
Yes it is doable. You will need an auto transfer switch to switch out the power grid in coming from your utility company. Then install a buddy plug on your coach wired 220vac 50 amp and have a cable long enough to run from the coach to the house to another plug wired to the auto transfer switch. The transfer switch control would need to be wired so the default power is from the power grid. Reason for the transfer switch is to keep from feeding power into the electrical grid from your utility and fry someone working on the down power lines. And of course, to keep the power grid from feeding back into your genset.

Check with your power company, they should have the info you need.

Using Generator As Backup For House Power
Eric,
I added a 50 and 30 amp plugs to the Bird that are used to power friend's trailers when we are camping. I added a Generator Transfer Switch to the house and can plug it into the coach to power the house. It will run the heat pump if nothing else except lights are on, we can cook and have hot water if the heat is off. (Our genset has a new 15KW back end on it.) Takes a little planning but it works. We have rental houses, I made a cable to back feed through the electric dryer plug when the power is off so I could work on them. Main breaker HAS to be off!!! Don't do this unless you are very comfortable with electricity. I brought the Bird home for the current Fort Worth storm but it wasn't needed. - Chuck Wheeler - 82 FC 31 SB Fort Worth, TX _____ From: WanderlodgeForum@yahoogroups.com [mailto:WanderlodgeForum@yahoogroups.com] On Behalf Of Eric Johnson Sent: Monday, January 15, 2007 9:06 AM To: WanderlodgeForum@yahoogroups.com Subject: [WanderlodgeForum] Using Generator As Backup For House Power Ice storms may bring loss of power to our home as in other areas of the country so I brought the coach to the house with the idea of moving into it if we have a problem.

Ralph,
I'm not an electrician, but in an emergency situation couldn't Eric just turn off the main disconnect on the outside of his house and then run extension cords? This should prevent sending power down the grid.

Eric,
Check out these two pages on my web site; http://www.pbase.com/iamflagman/image/41069743 http://www.pbase.com/iamflagman/image/50203372 Before anybody jumps the gun on the orange wire that I used, from the breaker box, to the 50 amp plug, the wire is ROMEX SIMpull 10/3 with ground which according to my electrician, is good for short runs like this in dry locations, it does not get hot when used to power my shop and sections of the rental property electrical system. the breaker box is just there for added security, as the power going to it is tapped off of the breaker box in the generator compartment.

Really what you need is to isolate the Gen from the power companys
system.. (The city Building & Safety Dept also has regs on this). The main thing you dont want to do is to "Back Feed" into the system, and reverse the power flow thru the poletop transformer.. The lineman fixing the problem may get Zapped by the 7 to 16K volts... Then this 6'10" 310# lineman will come and personally 'explain' to you just how unhappy he is!!!

Using Generator As Backup For House Power
Absolutely, I did this for several years with a
small 3KW generator on a Troy Built Tractor, two male plugs on an extension cord. Electricity entered the outlet, through the circuit breaker, though another circuit breaker to the furnace motor an TV. THEN I said what if someone accidentally throw the main? Voltage would go through the box through the street transformer building up to a high voltage. A repairman could be electrocuted. NOT ME, NOT ANYMORE, SOMEONE COULD DIE!! I did this 20 years ago and principals of electricity don't change in time. The only safe way is the right way, use a line transfer switch/relay. bob janes, greenville, sc --- In WanderlodgeForum@yahoogroups.com, "chet geist" wrote: > > Ralph, > > I'm not an electrician, but in an emergency situation couldn't Eric just > turn off the main disconnect on the outside of his house and then run > extension cords?

Using Generator As Backup For House Power
Lest anyone needs to hear it one more time, a manual or automatic transfer
switch WHICH LIFTS BOTH LEGS AND THE NEUTRAL, must be used to comply with many codes passed since the recent hurricanes. Generally, backfeeding the house through a "dryer" plug with just the "panel disconnected," does not comply, as that method normally does not also disconnect the panel neutral from the utility neutral. The penalty for being caught feeding any house circuit (versus feeding just an extension cord) other than through an "approved transfer switch" in Florida jurisdictions where the latest code has been adopted, is, the utility company will "pull" the meter. The re-application takes up to 6 months and is for INITIAL electrical service, which means; accompanied by plans signed-off by an engineer/licensed electrician certifying the house/business wiring meets all current electrical codes. Learned these goodies from the inspectors in 2005 when I added a house generator to replace the past "tried and true" Bird methods. I also stopped complaining about the outrageous cost of a 400 Amp transfer switch when I got the estimate to bring the 6-year-old house up to current electrical codes.

Using Generator As Backup For House Power
I do not know how the figure of a 400 amp transfer switch was determined, but
here you would require at least the size of the mains coming into the house, or the size of the generator, whichever is greater. (As John said, it must have both legs AND the neutral, this is so that no unbalance from the two legs is fed back either) Also an automatic transfer switch is not required, but a transfer switch whether it be auto or manual is. The transfer switch is two fold as well, first and foremost it is to stop electrocuting the lineman who is trying to repair the circuit, but second to pick up a long length of line, transformers as well as other loads, you could do great harm to your generator/engine.
