Greenlee 52033580 – Frequently Asked Questions

1) What voltage range will the Greenlee 52033580 non-contact voltage detector pick up?
The Greenlee 52033580 detects AC from 5 to 1000 volts, at frequencies between 50 and 500 Hz. That low 5 V end is what makes it usable for tracing low-voltage control and signal wiring as well as standard 120/277 V branch circuits, and the 500 Hz top end covers drive and generator frequencies above normal 50/60 Hz line power.
2) Is this Greenlee voltage detector rated for use on service entrance and utility side work?
It carries a CAT IV 1000V measurement category rating, which is the category covering the origin of the installation, service entrance, and outdoor overhead lines. That rating also covers everything below it, so panel work, feeders, and receptacle circuits are inside its envelope. It is C/US UL Listed and CE Listed.
3) Can I use this tester to verify how many volts are on a circuit before I work on it?
No. The 52033580 is a non-contact detector, so it indicates the presence of AC voltage between 5 and 1000 V but does not read a value. If you need an actual number, or a verified absence of voltage using a direct contact test, you need a multimeter or a two-lead voltage tester instead. Use the non-contact unit as a first pass and for live-wire tracing.
4) What does the adjustable sensitivity on this non-contact tester actually do for me on the job?
The 52033580 is an adjustable non-contact detector, so you can dial the sensitivity down when you are working in a crowded panel or a bundle of conductors and a fixed-sensitivity pen would light up on every wire near it. Turned up, it picks up voltage through insulation from further away, which is what you want when you are hunting a live conductor in a wall or checking a fixture whip you cannot reach. Fixed-sensitivity testers give you one setting and no way to isolate a single conductor.
5) What can I use the Greenlee 52033580 to check?
It is made for detecting voltage in outlets, lighting fixtures, wires and cables. Typical use is confirming a receptacle or fixture is dead before an electrician or maintenance tech opens it up, and tracing which conductor in a run is hot. It is a detector, not a meter, so it tells you voltage is present, not how much.
6) What battery does the Greenlee 52033580 voltage detector take?
One 1.5 V AAA cell. That is a stock battery any MRO crib or facilities cart already carries, so there is nothing special to order to keep it in service.
7) What is the Greenlee part number and UPC for this adjustable voltage detector?
Greenlee catalog number 52033580, UPC 783310127277. Country of origin is China.
8) Will this Greenlee detector fit in a tool pouch or shirt pocket?
Published dimensions are 8.900 x 5.200 x 1.100 inches, which is the packaged footprint rather than a bare pen-style barrel. Plan pouch or tool bag storage rather than a shirt pocket clip based on those numbers.
