Important safety warning — please read
Never use a non-contact detector as your only proof that a circuit is dead. These pens miss live conductors behind shielding, in metal conduit or in screened cable, they fail silently when the battery is weak, and they alarm falsely from induced voltage on nearby wiring.
Always prove dead with a two-pole voltage tester, and prove the tester itself on a known live source before and after. A pen is an indication, never a confirmation. Test each pen on a known live circuit before use.
Do not use the screwdriver tips on live work — they are not insulated for it. Isolate the supply and lock it off first.
Mains electrical work is regulated in many countries — if you are not qualified, use an electrician.
