Tolsen Tester Voltage Live Wire Non Contact 12-1000V 38110

Tolsen Tester Voltage Non Contact 12-1000V (Industrial)

MPN: 38110

Barcode: 6933528738527

Weight: 67g

Overview:

The Tolsen Non-Contact AC Voltage Detector tests for live voltage across a wide 12-1000V AC range without making direct contact with a conductor. It is built to the CAT III (1000V) standard and carries CE approval, making it suited to both commercial and light-industrial electrical work.

A three-level NVC sensitivity system selects automatically between high, medium, and low settings. This helps the detector perform accurately, whether you are working in a crowded junction box or checking through thicker insulation.

When voltage is detected, both a sound alarm and a light indicator activate at the same time. A built-in white torch illuminates dark work areas, and the prolate probe tip is shaped to reach terminals and cables in confined spaces.

Key Features and Benefits

• Wide Voltage Range: Detects AC voltage from 12V to 1000V, covering the majority of residential and commercial electrical systems.
• Non-Contact Detection: Tests for live voltage without touching the conductor, reducing the danger of electrical shock during checks.
• CAT III (1000V) Rated: Manufactured to CAT III (1000V) standard, verified safe for use in commercial and light-industrial environments.
• CE Approved: Carries CE approval, confirming the unit meets recognised professional safety requirements.
• Automatic NVC Sensitivity: Selects from three sensitivity levels - high, medium, and low - without manual adjustment, decreasing false readings.
• Dual Alarm System: Simultaneous sound and light signals clearly indicate voltage presence, even in noisy environments.
• Built-In White Torch: Illuminates dark panels, conduits, and cable runs so you can see what you are working on.
• Prolate Probe Shape: The elongated probe tip reaches into tight terminal spaces and conduit entry points with greater accuracy.
• Auto Power Off: Shuts down automatically to preserve battery life when the tool is not in use.
• Low Battery Indicator: Alerts you before power drops too low, so you always know the detector is reading correctly.
• Standard Battery Type: Runs on 2 x 1.5V AAA batteries, which are widely available (batteries not included).

Typical Applications

• Live Wire Checks: Confirming whether a cable or conductor is live before commencing electrical work.
• Circuit Breaker Identification: Locating the correct breaker in a panel before switching off a specific circuit.
• Conduit Testing: Checking for voltage through the outer wall of a conduit without cutting or stripping it.
• Junction Box Inspection: Pinpointing a live wire among multiple cables in a crowded enclosure.
• Wall Cavity Checking: Detecting buried cables before drilling or cutting into walls or partitions.
• Domestic Outlet Testing: Verifying whether a socket or fitting is still live after switching off at the consumer unit.
• Maintenance Work: Carrying out routine electrical checks on commercial and light-industrial installations.

How to Use

• Power On: Press the power button to activate the detector. The unit will run a brief self-check before it is ready.

• Position the Probe: Hold the prolate probe tip close to - but not touching - the cable, outlet, or conduit you want to test.

• Read the Alarm: If voltage is present, the detector will trigger both a sound alarm and a light signal at the same time. No alarm means the circuit is de-energised.

• Use the Torch if Needed: Activate the white torch to illuminate dark panels or cable runs so you can position the probe accurately.

• Power Off: The unit switches off automatically after a period of inactivity, or you can power it off manually to conserve battery life.

Frequently Asked Questions (FAQs)

• What does a non-contact voltage detector actually detect?
  It detects the electric field that a live AC conductor produces. When that field is strong enough, the detector triggers its alarm without the probe needing to touch the wire or terminal directly.

• Can this detector be used on DC voltage?
  No. This detector is designed for AC voltage only. It will not respond to DC circuits, so it should not be used to test batteries, solar panels, or other DC sources.

• What does the CAT III rating mean in practice?
  CAT III covers distribution-level circuits such as fixed wiring, distribution boards, and equipment in commercial buildings. It means the detector has been tested to withstand voltage transients common in those environments.

• Why does sensitivity level matter when testing in a junction box?
  In a crowded enclosure, cables sit close together. A high sensitivity setting may pick up the field from an adjacent live cable. Switching to a lower sensitivity helps you identify which specific cable is live rather than detecting a neighbour's field.

• How do I know if the batteries need replacing?
  The built-in low battery indicator will alert you when the charge drops below the level needed for accurate readings. Always check the indicator before using the detector on a job.

Summary

The Tolsen Non-Contact AC Voltage Detector (38110) supplies a straightforward, no-contact method of checking for live AC voltage between 12V and 1000V. Built to CAT III (1000V) standard with CE approval, automatic three-level NVC sensitivity, dual sound and light alarms, and a built-in torch, it gives electricians and maintenance professionals a fast and safe way to test circuits before they work on them.
