Portable Generators

The spouse was out the door quickly yesterday morning when our power went out, was in Waldorf by 7am, to Lowes, Home Depot, and Tractor Supply came home with a Generator and Kerosene heater.
Power was back on by 7am. only out about 3 hours.
We have talked about a portable generator ever since Isabelle came thru and we were without power for 3 days or so. My question does anyone know about what it cost for a electrician to hard wire the breaker box?

My father and brother do this. :yay: We just got a generator but don't have it wired yet. There's a kit to do it correctly..costs about $200 for that..not sure what the labor would cost but I can ask.

If you don't mind, let me know too. I've been putting it off too long already. :howdy:

We have a tractor that has a PTO, and have been looking at generators that would be powered off of the PTO. Why pay for another engine if I don't have too?

You have a gas powered one? Lucky.

There are a couple of ways to approach this.
You add a new smaller panel and choose the circuits that are most critical to you and your family.
The size of your new generator will determine how many circuits you can have. What is the kw on your generator?

Then you may not want to go through the extravagant expense of a new "emergency panel" if you have a small generator. Generally, the Home Depot variety will only give you 30amps. Hopefully you don't have a heat pump.

If this be the case, the heat pump draws more than the average portable generator. There are significant advances in generators because they have become a househould commodity as of late. Yours may be capable of 50amps.

There are "whole house" generators available for a few grand. But they mount on pads and are stationary. Actually, because of advances, they are not much more than a high end portable.
I have a cheap $495 generator for doing jobs. My $1300 dollar generator is for back up power (it will handle the central air and fridge and a few lights and tv of course).
For $2500 you can get a nice generator that will handle most any thing you throw at it and it comes with all the hardware needed and a panel kit.

You can buy panel kits that will allow you to safely transfer to back up power and then when normal power is restored you reverse the breaker and it will safely take your generator "off-line" so that you don't accidently "back feed" SMECo.

These can range from 150 to 500 + in material costs then you should get THREE estimates. (get the estimates, you would be amazed!)

If the contractor can't make it to give you an estimate.....chances are they cannot make it to do the job. Estimates are FREE. If the are not free you should not do business with that contractor.

There is another way to hook it up to your existing panel. It does not cost much for material (under $100 usually) However, you must be of "mind" to turn off your main switch. You, infact, take the place of the safety mechinisms that would have been incorprated by a transfer switch that is included in the more expensive kit.

There you have it.
Just remember, It is important that you size your "load" to not exceed the capabilities of you generator.

Its a 6250 watt max Coleman Powermate, with 5000 rated wattage. I do not have a heat pump.
Id just like to be able to run the necessary things should the power go out, even if I would have to switch breakers on and off to accomplish this. The smaller panel and being able to choose the most critical ones to use sounds good. Thanks for info River Rat. :yay:

Interesting concept
We've got a 25HP diesel with 20 Shaft HP off of the PTO.. can power up to a 15kW I believe. And with most everything out there, the engine is usually where the expense is, buy one engine with a PTO and run multitudes of things with it.

I do not need my 20K tractor with 3000 hours on it when the power goes out

You can also backfeed your house through a 220 outlet if you have a 220 feed from the generator. You shut off the main circuit breaker and all the individual breakers in your maing house box so you are disconnected from the power grid. Then you power up your generator and plug it into the 220 outlet (like if you have one in your garage). You can then switch your circuit breakers back on to power the rooms/appliances you want (leaving the main off so you aren't backfeeding the power lines). With a 5-6K generator, you should be able to run most of the power to your house except your A/C. It will definitely run your refrigerator and lights. You may have to shut off a bunch of stuff when you want to run your microwave or stove, but it works. Just leave the main breaker off so you don't injure linemen working on the grid.

Do those guys not ground the cables when they are working on them? I sure think I would want to.

The 6250 will give you a spurt of 26 amps at 240 volts. The 5000 rated = just under 21 amps. This is not a lot of power and definately will not run your heat pump, electric range etc.... You can turn on lights and use some outlets but no space heaters!

Article 702 of the National Electrical Code requires use of a transfer switch inorder to protect linemen and prevent fires. If you choose not to use one and you shock somebody you face massive liability. The switches aren't that expensive.

My supervisor from work does this. I think he said he had to have some kind of switch installed or something.:shrug:

We are going to go with a stationary generator, big enough to run the fridge, freezer, SUMP PUMP(!) and provide power to most of the outlets.
