With the voltage tester T 6-600 using the open clamp-on ammeter AC voltages up to 600 V, without with test leads a contact to live points.
The time-consuming opening covers or releasing the screws on terminal strip is not necessary.
The forked opening is enough for conductor cross-sections up to 120 mm2 and for currents up to 200 A.
This will significantly change their work.
More secure.
Faster.
Easier.
