Live Wire Tracing Kit for 120VAC and 220VAC Circuits

The WUQ 3388 Fox & Hound HotWire kit traces energised conductors from 0 to 250 VAC through walls, floors and ceilings. A tone generator produces Pulse or Warble signals while the handheld probe uses adjustable sensitivity and a signal-strength LED to pinpoint wires up to 1000 feet away. It suits electricians and technicians who need to identify live circuits without shutting down power.

Battery Operated Probe with Adjustable Sensitivity

The probe runs on an internal battery and offers a thumbwheel gain control for precise signal detection in noisy environments. Visual and audible continuity checks plus TrueTrace and TripLatch functions confirm wire integrity without extra instruments. The kit is not designed for low-voltage data cabling or de-energised wire mapping beyond the stated voltage range.

Questions about this item

How do I connect the 3388 transmitter to a live 120 VAC or 220 VAC circuit without tripping the breaker?

Plug the transmitter into the outlet or use the alligator clips on the hot and neutral conductors; the unit injects a tracing tone at low current so the breaker stays closed.

Which parts of the 3388 kit will need fresh batteries first during regular use?

The Hound probe runs on a 9 V battery that powers the sensitivity thumbwheel and signal LED; replace it when the indicator dims or tone detection becomes unreliable.
