I use the latest Suretest.
If you try the conductor impedance test for the ground it should trip GFCI and AFCI in a much more reliable way.
But the isolated neutral test (for GFCI) is good.
I have scoped this out and set up controlled tests. Even though the cheezy connections inside give a no-ground condition sometimes (easily correctable with some fine wire and solder), I have found it to be the best all around tester available.
Just my 2 cents.
Can there be voltage if there’s no load? Confused.
If there is a potential (i.e. a difference in voltage between two different conductors, as measured in voltage (i.e. electrical ‘potential’) there is ‘voltage’.)
Just because there is no load (i.e. “work to be done”) does not mean that there is no ‘potental’ work available to be done.
Think of a garden hose. It has an open water supply. It has ‘pressure’ (i.e. ‘voltage’) but the water is not floating because the nozzle on the end of the hose is not open. If one were to open the nozzle, the water would flow and work could be done (i.e. hosing down your little brother who had really P*ssed you off).
Hope this helps;
It did. Thanks.
