Three-piece test lead set for Fluke 1550B

This set provides three test leads in red, black and green that connect to low leakage probes. Three matching alligator clips share the same colour coding. It is supplied as the replacement lead kit for the Fluke 1550B megaohmmeter and is rated for 5000 V DC and 20 A current.

Sustained high-voltage insulation testing

The low leakage probe design keeps measurement errors small during extended insulation resistance tests at the full 5000 V rating. Each lead is 2.6 metres long, giving operators distance from live equipment while the 20 A capacity handles continuous current without overheating the conductors.

Simple clip-on installation with colour-coded safety

Alligator clips open to 26 millimetres and snap onto the probe ends without tools, while the red, black and green coding prevents accidental phase mixing. The only common issue is debris in the jaw faces reducing grip, so a quick wipe before use keeps the connection secure.

Questions about this item

How much heat or power draw should I expect from the 20 A test leads during all-day use?

The leads themselves draw no power and generate no heat; they only carry the current you are measuring, rated up to 20 A at 5000 V.

What meter or instrument must I already own for this TL1550B set to work?

It is designed as a replacement lead set for the Fluke 1550B megaohmmeter.

Will the 26 mm jaw opening alligator clips fit the older bus bars I still use?

The clips open to 26 mm, so they will grip bus bars or terminals up to that thickness.
