Klein Tools RT310 AFCI and GFCI Outlet and Device Tester for North American AC Electrical Outlet Receptacles

Klein Tools RT310 AFCI and GFCI Outlet and Device Tester for North American AC Electrical Outlet Receptacles

Q: does this actually place a load on the circuit for for voltage drop?

It simulates a 12,15, and 20 amp load and displays the percentage drop, according to the operating instructions.

Q: Will this indicate open neutral or open ground when circuit is not energized?

Way late on answer this. If you’re talking about (Klein Tools RT210 Outlet Tester) then no, it has to have power on the circuit as this is not battery powered to show the tester how it’s wired.

Q: Does this simulate and test both serial and parallel arc fault conditions?

This tester plugs into an outlet on the circuit under test, so it seems to me that automatically makes it a parallel device. Therefore it can only simulate an arc fault such as might occur in a parallel device, i.e. what you normally plug into an outlet. (A typical faulty item being be a lamp with a frayed power cord.) I believe the tester would have to be wired into the circuit in series to simulate a serial arc fault. I don't know the nature of the tester's design but it may be that tripping an AFCI unit (an AFCI outlet, for instance) with a parallel fault simulation may also prove the AFCI's ability to respond to a serial arc fault, at least in part. Disclaimer: I'm not an electrician or EE so you may want to dig farther on this subject, but I believe I have the basics right.

Q: Does this protect trip a gfci protected receptacle with an open ground?

No it will not. No tester will trip a GFCI with open ground. You have to use the button on the receptacle/breaker in that case. Make sure the outlet is labeled with "no equipment ground."
