Yes Thanks like I said I did not see the problem unless the GFI built int the power Bar could disrupt it.
GFCI will not break the equipment ground, just the hot and neutral - so the probe will still "work" with a GFCI extension cord or power strip :)
So Since you like electricity . I have been trying to explain in the past to people the difference between a GFI, and an ARC protector. Two entirely different things.
Correct, but the distinction becomes a bit murky, in that some arc fault interrupters, also contain ground fault interrupters - in other words they are combo devices. But, yes the two types of protection serve very different purposes.
In very general terms:
The ground fault interrupter simply checks to make sure the amount of current that enters that flows
out through the hot wire is the same amount that flows
back through the device. If there is a difference, it means current is faulting (going
someplace it shouldn't, like
ground) and trips the circuit.
The arc fault interrupter scans what is connected to it for specific types of pulses in the electricity that would indicate sparking. These devices have improved over the years, but can still be prone to nuisance tripping with devices that create sparking - for example, brushed electric motors, devices that have mechanical relays or other pulsing type of current usage... vacuum cleaners, arc and fluorescent lamps, power tools and motors, tv and appliances, some poorly filtered AV equipment, microwaves, etc.
I have had personal experience with why we all should install them. You can do one receptacle or the entire house. Feel free to give your opinion, I developed mine after sharing my Near burnt house down experience with a master electrician friend of mine. All caused by not having a drip leg on a power head electrical cord
Let's make a couple of very basic distinctions here.
1 - standard circuit breakers in your electric panel are there to
protect the wire, not you.
2 - circuit breakers in appliances are to
protect the wires/components in the appliance, not you!
3 - GFCIs are there to
protect you from shock or electrocution.
4 - AFCIs are added protection
to protect the wire and the structure from arc related fires.
The issue with the AFCI is that it is more prone to nuisance trips that the GFCI. However, saltwater and salt creep, especially on or near plug strips, ,etc. can easily cause current to flow from HOT to NEUTRAL through the salt creep and/or the dampness can allow carbon tracking between the two. If this faulting does not reach the ground lug, then it will NOT trip the GFCI but does have the real chance of starting an arcing fire. This is where arc fault protections comes into play.
As I said, modern arc fault devices are less prone to nuisance trips than prior generations. I would certainly agree that protecting your home and person by using a combination of both arc and ground fault protection is a good idea. One could always remove the arc fault protection and just go with gfc if nuisance trips are a problem for a given setup.
These individual or combo devices can be in breaker form (whole circuit) or individual receptacles.
