I am going to back feed my panel with the 50 AMP plug on the generator. Do I use a 50 AMP or a 30 AMP breaker to back feed my house?

You will need a 50 amp breaker. Back feeding is very dangerous and illegal if not done to code. This question that you asked makes me think you have little experience so please be sure to do as much research as possible before you attempt this.
1084192
You will need a double breaker with a minimum of 25 amp on each side. I have a double 30 on 1 panel and a double 40 on the other (I have 2 hookups) The Generator has its own breaker as well if over drawn.

I put in a interlock kit that way you do not have to worry about feeding power to the line to kill the people working on the line. You can buy a plug in for a few bucks. Then you need a couple circuit breakers and you are done. Back feeding is very dangerous.

You'll need a 50amp breaker, don't back feed, install an interlock. You need to make sure you can't have your generator breaker on at the same time your main breaker is on.

Why not contact your local electrical provider, inform them of your intentions, and see what THEY have to say about the issue? You MAY be headed for some dangerous situations, not to mention a lawsuit if someone gets hurt. THEY could best advise you on how to proceed, and might even do the work FOR YOU, to ensure it is correct... Back-feeding is dangerous, and in many locales ILLEGAL....... Can you say "lawsuit"? Your house burns down because of an electrical issue, and burns TWO OTHERS with it.... See the bizarre outcome? ... Let THEM tell you how THEY want it safely done..... jus' sayin'....

You do not want this model. It is only rated at 5000 watts and 20 amps. Assuming your generator is rated at 30 amps, purchase the largest 30 amp box you can. The amps are just as important as the watts. You want to supply as many circuits as you can. Take into account that the chances of all your appliances running at peak wattage all at the same time are slim to none. The most important thing to know is to turn them on in the proper sequence. Turn on the appliances with the highest load first, waiting for the wattage spike. Turn them on one at a time until the wattage drops and you should be good. When it comes to electricity, bigger is better. You do not want this model. It is only rated at 5000 watts and 20 amps.

It is not recommended by the manufacturer to use any breaker larger than a 30 amp double pole. I don"t operate my stove on the back up generator. With this transfer switch and a 8500 watt portable generator I can run most everything else, not all at the same time though. That includes the AC.

The generator can produce 17500 watts but... there is no single outlet that can output 17500 watts Here is a summary of the issue: http://www.dslreports.com/forum/r27334996-Generac-GP17500E-Generator And realistically there is no feasible residential portable generator solution for using a cable (temporary connection) for more than 50 amp/12kw; above 50amp I would focus on a standby genset (i.e. hardwired transfer switch to home load center). I wrote this about the challenges of going over 50 amp for residential portable generator : http://www.diychatroom.com/f18/clarification-cam-lock-usage-private-residential-applications-170121 "enough to power a house" that depends on your home's load and there are plenty of load calculations on internet that can help you estimate (or an electrician tell you OR if you want to know for sure and be able to track and monitor then install a TED - "The Energy Detective" into you main breaker panel). You need to do is determine what are your emergency circuits needs (i.e. the musts for emergency power), e.g. my emergency circuits are a 5-ton heat-pump (AC/heat-pump unit & fan but not heating coils), electric water heater, water pump, etc. - for me non-emergency would dryer & electric cooking range & oven. The big heavy hitters you need to look-out for are typically HVAC system (if the heating is non-electric then good chances you will not have any over-load issues) and water heater. Given there is no single output greater than 50 amp and given the location of the 50 amp outlet (i.e. 14-50r) on the GP17500E model - if I had to do all over again then I would go with the GP15000E model instead.

My best guess would beb that the 50amp version would not work for 30amp application. However, my 50amp works great have you considered the 30amp version for your RV? It should work just as great for you if you have a true 30 amp RV. I Have never tested the adapter with a 30 to fifty plug. We are parked where I could test That I have never tried it because of the built in set up delay start protector I don't think it will turn on. Would you like me to test it with a 30to50plug adapter on the 30amp circuit plug?

I have never grounded my generator. It is grounded to the frame by the manufacturer. Unless your local municipality requires it I don't see the need. HOWEVER, if you set it up improperly by choosing not to connect it to the house by use of a transfer switch or other isolating equipment you can cause a major problem and fire at the generator. What I am saying is never back feed it into the house, you are just looking for problems. Having said all that it can be grounded by driving a grounding stake deep into the ground and attaching it to the grounding lug on the generator's frame.

If the entire house goes out you first must trip the main breaker to prevent back. There is ywo sockets with twenty amp it should freg, heater,light. Direct off drop cords. I recommend. This generator

Its a 21amp unit at highest pick a watt. 30 amp 2 pull breaker will do just fine.

No, the plug is part of the assembly and included. This allows you to simply connect the wiring to the back of the plug and mount the box on an exterior wall of your house. The installation was very simple. The only thing you need to check is if you want a 30amp connector or a 50amp connector. This product is the 50amp version of the plug. The reason I mention this is that the cables you use to connect to your generator will need to match this plug. Hope that helps, Rick

No need to spilt the circuits. It has a 30 amp input already. I have the style prior to the newer updates. My generator requires a RV style 3 prong adapter, as I use it on my boat. The newer generators have the 30 amp female input built in.

William, This particular unit uses the 50 amp plug there is a different unit that uses the 30 amp plug

Your generator will only put out 41 amps at full load no matter how many 30amp receptacles you have. The more items you use in your RV at the same time the more amps you will use, up to 41 amps max.

Yes you can. It can handle 30 amps with no problem. But don't use a 30 amp transfer switch for a 50 Amp generator- BIG trouble!
851001
iit all depends what size generator you are using. if its 7500 no . it woun't work need 30 amp 2pole breaker
2025437
Yes, it can be plugged into a 30 amp breaker but you can only use up to 5000 watts of the 7500 setings. Also if you use the 7500 watt selection you must have 8 gauge feed wire rather then stated 10 gauge.

15amps pre side. Totals 30amps total. The thing I found out about these little inverters is not to run them on a weak power supply, if an extension cord is needed, use a VERRY heavy cord. And the manufacturer " implies " it is the ground by stating adding a ground to lugs in back of unit. Believe me 30 is plenty! But I use a generator with 30 and40 amp outlets and always a ground stake. O by the way,the foot rheostat pictured in the ad does not come with it had to go on line to a German supplier to find one. So if your cripple like me and a foot switch is critical, you may want to do some further looking. Otherwise this machine is amazing. 15amps pre side. Totals 30amps total.

I would definitely recommend adding a sub panel with all of the critical circuits you would need in the event of a power failure. This way you can pick and choose what appliances to run when you need them. Also eliminates the need for multiple extension cords. Generac makes a nice kit to use with that generator
