## Questions & Answers

**Q: I was told by a salesman at lowes (credentials unknown) that i should not use these devices because i could backfeed through the neutral. true?**
A: He could have possibly been referring to bonding the neutral to ground in 2 spots, which is not only against code but could result in circuit breakers not tripping on a ground fault (when they should because of two separate return paths when running on the generator.  The way to avoid this is to make sure that your generator has a floating neutral (not bonded to ground in the generator) and that the neutral is bonded to ground inside the distribution panel in your house at one spot only (99% of the time neutral will be bonded to ground in the panel unless the electrician who installed it was grossly incompetent or something extraordinary happened in your panel).  The only catch is that if you are using the generator and NOT back feeding your panel (just running extension cords to various appliances) then you do want the neutral bonded to ground at the generator.  Fortunately some generators let you add/remove the jumper yourself to do this.  Disclaimer: This is not recommended unless you are sure you know what you are doing, with everything de-energized, etc.).

**Q: My box is a bottom feed and the main breaker is on the bottom.  Will it still work?**
A: Yes it will still work fine as long as the generator breaker to feed the bus bars is right above the the main breaker and in the slot to the left to allow lockout.

**Q: 2 year warranty is all? Why**
A: It’s a piece of metal. It probably will never break. Quit whining

**Q: Will this work for my square d series 1 200 amp qd load center?  type 1 enclosure?  cat. no. qoc40uf. my spacing is only 1 1/2 inches?**
A: I have the 200 amp square D the same and it worked fine. I did have to piggy back a couple of circuits into a split breaker to make room for a 50 amp breaker. I ended up using a spare 40 amp breaker i had for a hot which was not being used. My panel had been installed upside down so it worked out to be bottom left instead of top right.

    Should have installed this last year
  

*by M***L on Reviewed in the United States on March 9, 2021*

I love the whole concept of the Interlock System and the whole setup was fairly simple for me to do... although it's recommended to have an electrician install it for you.  I finished the install yesterday and tested it today.  I connected my 7500W Generator and it powered almost the entire house.  I have mostly gas appliances so the load is much less.  However, I was even able to run the Central A/C.  The whole system cost me around $300.  I know an electrician that offered to do the install for $650.  All things considered, I prefer this to either an Inline System or a Transfer Switch.  For me, this just makes more sense.  Didn't do it in time for the freeze but, where I live, I'm pretty much guaranteed a couple of big power outages each year.

*by B***. on Reviewed in the United States on April 21, 2021*

Well made, with all the labels necessary to guide you, and in the case of fire department, the info they needed when on property. If your handy with a drill, and screw drive, you can do it. “ IF YOU DON’T KNOW HOW TO WORK AROUND ‘ELECTRICITY’, GET A PRO LICENSED ELECTRICIAN TO DO...You will be drilling into the face plate of your entry electric box. My son is an electrician, and I am “very familiar” with wiring...Be Safe. WORKS GREAT WHEN INSTALLED PROPERLY.

    Fit perfectly and easy to install
  

*by B***Y on Reviewed in the United States on October 1, 2020*

This item works perfectly when installed as per the supplied directions. It is expensive for what it is, but the interlock is necessary to make the generator power input breaker almost foolproof.
