Rack-A-Tiers 99000 – Frequently Asked Questions

1) Will the Rack-A-Tiers 99000 voltage sensor detect 120V and 277V branch circuits?
Yes. The 99000 AC sensor covers 50 to 1000V AC, so standard 120V residential circuits and 277V lighting circuits both fall inside its range, as do 208V, 240V, 480V and 600V systems.
2) Is the Rack-A-Tiers 99000 a non-contact tester, or do I have to touch the conductor?
It is a non-contact voltage tester. The 99000 senses the presence of alternating current near a conductor, so you can check an energized wire, device or panel without putting a probe on metal.
3) Can the 99000 AC sensor tell me the actual voltage on a circuit?
No. The 99000 is a presence detector, not a meter. It tells you whether AC is present anywhere from 50 to 1000V, but it will not read out a value. If you need the actual voltage, current or resistance, use a multimeter or a clamp meter instead.
4) Is the Rack-A-Tiers 99000 suitable for a low voltage circuit like 24V control wiring?
No. Detection starts at 50V AC, so 24V thermostat and control wiring, doorbell transformers and most Class 2 signaling circuits sit below the sensor's range. A tester or meter rated for low voltage work is the right tool there.
5) Will the 99000 sensor pick up DC voltage, like on a solar array or battery bank?
No. The 99000 senses alternating current only. For DC circuits, PV strings on the array side, or battery systems, you need a DC-capable meter or tester.
6) Is a non-contact sensor like the 99000 enough for lockout/tagout verification in a commercial facility?
Treat it as a first check, not the final one. The 99000 confirms AC presence from 50 to 1000V quickly on panels, wiring and devices, which is what makes it useful for pre-work circuit verification. For absence-of-voltage proof under an LOTO procedure most facility programs require a direct-contact instrument on the conductors, so the sensor is the screening step ahead of that.
7) Can one voltage sensor cover both residential service work and 480V industrial panels?
The 99000's 50 to 1000V AC span covers residential 120/240V, commercial 208/277/480V and 600V industrial gear, so a crew working across all three does not need separate sensors for each. It is intended for residential, commercial and industrial electrical systems.
8) What model and part number do I order for the Rack-A-Tiers AC voltage sensor?
One model covers it: Rack-A-Tiers 99000. The manufacturer part number is 99000, and there are no finish, range or kit options to specify.
