Compatible Fluke Multimeters

The Fluke AC87 Bus Bar Probes connect to a wide range of Fluke handheld meters including the 107, 110, 114, 115, 116, 117, 175, 177, 179, 289, 365, 373, 374, 375, 376, 381, 705, 707, 709, 712, 787, 789, 83, 87, and 902 series. They provide a secure connection for electrical testing in automotive and industrial environments. The black and red colour coding simplifies polarity identification during measurements.

Electrical Ratings And Safety

These probes are rated for a maximum current of 5 A and a maximum voltage of 600 V. They support hand-held operation up to 1000 V AC or DC and hands-free operation at the same voltage level. The design meets safety requirements for CAT III and CAT IV measurement categories where applicable. Users must observe the stated limits to maintain protection during live circuit testing.

Sustained Load Behaviour

Under continuous load the probes maintain stable contact resistance up to the 5 A rating without overheating. The bus-bar style jaws grip conductors firmly, reducing the risk of intermittent readings during extended monitoring sessions. Insulation remains effective at the rated 1000 V for hands-free use, supporting long-duration diagnostic work. They are not suited for currents exceeding 5 A or for voltages above the specified limits.

Questions about this item

How do I attach the Fluke AC87 probes to a bus bar without damaging the 5 A contacts?

Press the spring-loaded jaws squarely onto the bar until the insulated grips lock; forcing them at an angle bends the contact tips and reduces the 5 A rating.

What part of the AC87 set wears out first and needs replacement?

The stainless-steel jaw springs lose tension after repeated clamping cycles, so the pair should be replaced when the probes no longer grip a 1000 V bus bar firmly.

At what voltage does the insulation on these probes reach its limit during continuous measurement?

The probes are rated for 1000 V AC/DC hands-free and 600 V hand-held; sustained use above those levels degrades the insulation first.
