can it be used in a circuit already protected with a gfci in the house wiring ???

Yes. All this device does is compare current out with current coming back, and shuts off the power when they differ (due to current going somewhere else). Two GFCI devices in line might not necessarily increase safety, but they shouldn't be a problem.

Yes, but not sure it would provide any further protection over your existing GFI breaker. However, if your problem is the house GFI circuit being tripped all the time, it might keep your house GFI from being tripped. For example, if you were using a power tool connected to this device that tripped the GFI, it might trip only this device without tripping the entire GFI circuit in your house. Don't know that for a fact, since never tried and not an electrician, but seems possible.

Yea, I would assume. I used it to protect a PID controller. Standard outlets are 15a at 110/120v and you pick the fuse to go in it. 1a to 15a fuses... work fine for me

Hello J. Kiser - Yes, if you wire this unit into a breaker box that has a bonded neutral it will trip the GFCI on the inverter because it also has a bonded neutral.The inverter cannot be connected or tied into another unit that has a bonded neutral.Please go to our website - http://gpelectric.com/contact-us - and call or email us for more information.Go Power!

only if you have huge power draw pulling power through them. The Amp rating of switches and relays etc are the max rating for the circuit. You are safe as long as what ever is actually using the power uses less than the lowest rated part of the circuit you will be just fine.

I would think so. This unit just extends the existing electrical circuits, so you would still have your ground fault protection. However, if the ground fault function in the main outlet was activated, you would need to remove the surge protector to access the re-set switch.

I suggest you contact the manufacturer for your answer. Personally, I would only plug those units into a 15-20 amp dedicated wall socket with GFCI protection. I use this surge unit for my computer, monitor, external hard drives, wireless router etc. with excellent results.

No. It would not be a good idea because you would only have 20 amp protection for that circuit.

From what I understand, there shouldn't be an issue. The product works within the circuitry...wiring. Theoretically, any apartments that are on the same line, may benefit as well. Hope this helps.

No. However, if any circuit has multiple devices which collectively cause it to pull more amps than it is rated for, it could trip the breaker (or blow the fuse).

No.Even if you would modify this unit to fit (NOT recommended) it would not protect anything because there would be no ground on the unit. And even if you modify your outlets, AGAIN, it would NOT protect the equipment because there is NO GROUND connected. Why not purchase a cheaper unit that just distributes electricity but does not protect from surges.

No this is not GFI (Ground fault interrupter), you would have to install separate GFI behind the switch or between the switch and fan. -- It is a very good timer switch, and I have wired several for use in bath exhaust fans. It's advantage is that it will handle larger loads (bigger fans) then most switches.
127832
Yes, but you need to insure that the circuit you are plugged into can handle the load. If not, you will trip the breaker.
1126058
absolutely. The breakers prevent from overloading the circuit ONLY. This device protects against surges, high voltage, low voltage, open neutrals or grounds, etc. Small price to pay to save several thousands worth of electrical devices

Yes - but you will need to take in to account the whole environment. i.e. don't place where it may become submerged; the instructions/directions specify that it be used on a ground-fault interrupt (GFI) protected circuit.

i would not recomend it on a live circuit. but if you new it was a dead circuit, it would work. pervided you could get close to the wire you were tracing.

No...because it requires a ground to work correctly.It will plug in & work but you would notice the red fault led light up,&the; manual says that for it to work correct you need a ground.You would be cheating your self & your equiptment for the protection,that's what were looking for.I'am guessing your home has later wireing,which didn't require grounding,like of todays.Sorry too give you the bad news,but for it too really protect & work correct would require a good ground system.And with the cost of electronics we don't want to cheat ourselfs.The parts inside require ground system to work correctly.Good luck,on finding solution.

This truly need a designated circuit. If not you can't use any other devices on that circuit. It will trip breaker. I had one installed upstairs and downstairs a few yrs ago for ac and heat. I plugged it into a outlet with just my computer and cell phone charger on it and it tripped. It maxes out 15 amp circuit. But it work very well keeps 900 sq ft room nice and comfy.
