Klein Tools RT250KIT – Frequently Asked Questions

1) What comes in the Klein Tools RT250KIT electrical test kit?
Two tools: the RT250 GFCI receptacle tester and the NCVT3P dual-range non-contact voltage tester with flashlight. The RT250 checks receptacle wiring and trips GFCI devices with an LCD readout; the NCVT3P is the pen-style tester you carry for live-circuit checks. Between them you can verify an outlet is wired right and confirm a conductor or device is dead before you touch it.
2) Can the RT250 receptacle tester be used on 240V or two-wire outlets?
No. The RT250 is built for 3-wire, North American 120V outlets only, and it carries a CAT II 135V safety rating. Don't put it on a 240V receptacle, a non-grounding two-wire outlet, or anything outside standard North American residential/commercial 120V. For higher-voltage work use the NCVT3P side of the kit, which is rated CAT IV 1000V.
3) What voltage range will the NCVT3P non-contact tester detect?
Two selectable ranges: 70 to 1000V AC for standard line-voltage work, and 12 to 1000V AC for low-voltage circuits like thermostat, doorbell, and control wiring. The low range is the reason to carry this one over a single-range pen, since a 70V-minimum tester won't see a 24V control circuit at all. It signals with both a visual and an audible indicator.
4) What wiring faults will the RT250 pick up on a receptacle?
It gives a clear indication of wiring conditions on a 3-wire 120V outlet plus a large backlit LCD voltage readout, and it includes Klein's patent-pending detection of an open neutral / open ground combination, a fault a lot of basic three-light testers miss entirely. That combination is the reason to reach for this over a plain neon three-light plug tester on punch-list or turnover inspections.
5) Is the NCVT3P safe for work inside a panel or at the service entrance?
The NCVT3P is rated CAT IV 1000V, which is the category intended for the origin of the installation, service drops, and outdoor conductors. The RT250 receptacle tester is a different story, CAT II 135V, so keep that one on the load side at 120V outlets only.
6) Does this Klein tester kit detect AFCI faults or just GFCI?
GFCI only. The RT250 tests GFCI devices and reports the time required to trip them on its LCD, but neither tool in the kit performs AFCI testing. If your inspection scope includes arc-fault devices, you'll need a separate AFCI-capable tester.
7) Will these testers survive a drop off a ladder?
Both tools are rated for a 6.6 foot (2 m) drop, which covers a fall from a stepladder or off a panel onto a slab. The RT250 housing is ABS and the NCVT3P is polycarbonate, and the NCVT3P has a pocket clip so it rides in a shirt pocket instead of loose in the bag.
8) What batteries does the RT250KIT kit take, and are they the kind I can swap on site?
The kit runs on 4 AAA cells, so both tools take standard alkalines you can pick up anywhere rather than a proprietary pack. Worth keeping a spare set in the bag, because the NCVT3P's flashlight draws on the same cells and can be run independently of the voltage detection function.
9) How big are the two testers in the Klein RT250KIT?
The RT250 receptacle tester measures 4.5 x 2 x 1.1 inches (11.4 x 5.1 x 2.8 cm). The NCVT3P voltage pen is 5.70 x 0.93 x 1.09 inches (14.5 x 2.4 x 2.8 cm), pen-sized and clipped. Kit weight is about 0.617 lbs, so it's a pouch-and-pocket pair rather than something that needs its own case slot.
10) What is the Klein part number to order for this two-tool kit?
Order it as Klein Tools RT250KIT. That single part number covers both pieces, the RT250 GFCI receptacle tester and the NCVT3P dual-range non-contact voltage tester with flashlight. There are no finish or configuration options to specify.
