Extech CB10-KIT Electrical Troubleshooting Kit

Fits residential and light-commercial electrical walk-throughs that need one case covering breaker locate (CB10), continuity/wire trace (CT20), and non-contact AC voltage (DV20) on North American 110–125 VAC receptacle circuits.

Key advantages

Kit mix — Electrical troubleshooting kit (breaker finder + continuity/wire tracer + NCV detector).
Coverage — Kit: CB10 breaker finder 90–120 VAC / 47–63 Hz; DV20 non-contact AC voltage 100–600 VAC; CT20 continuity/wire trace (remote probe up to 3 cables).
Indication — Audible/visual breaker locate; receptacle wiring LEDs (6 fault conditions); GFCI trip test; continuity beeper; NCV LED + flashlight.
Power — CB10 receiver 9 V battery (transmitter line-powered); CT20 9 V; DV20 2×AAA.
Approvals — UL (CB10, DV20); CE; CAT III 600 V (DV20).

Typical applications

Panel work locating unknown breakers with CB10 transmitter + receiver.
Cable/continuity tracing with CT20 remote probe (up to 3 cables).
Quick AC presence checks with DV20 NCV (100–600 VAC) and flashlight.
Service kits for 110–125 VAC North American receptacle circuits.

Selection guide

Voltage style — CB10 is for 90–120 VAC / 47–63 Hz receptacle circuits (110–125 V NA style) — not 230 V export receptacles.
Kit members — CB10 + CT20 + DV20 + batteries + case per OEM kit listing.
Environment — CB10 operating 5 to 40 °C (41 to 104 °F); storage −20 to 60 °C.
Safety — UL (CB10, DV20); CE; CAT III 600 V (DV20); DV20 listed CAT III 600 V.
Stand-alone CB10 — If you only need breaker find + GFCI, compare SKU 24338 (CB10 alone) before ordering the full kit.

Common mistakes

Ordering for 230 V / non-North-American receptacles — CB10 transmitter is NA 110–125 V plug-in style.
Expecting CT20 to replace a full TDR cable certifier — it is continuity/wire trace with remote probe.
Treating DV20 NCV as a calibrated voltmeter — it indicates presence, not precise voltage.
Assuming the kit ships without batteries — OEM kit lists batteries included; confirm on RFQ if critical.

When to RFQ / what to tell us

Confirm 110–125 VAC North American receptacle use and that all three tools (CB10/CT20/DV20) are needed.
Whether breaker-find only (CB10 alone) is enough vs full kit.
Quantity, ship-to, and case/battery preferences.

FAQ

Q: What is in CB10-KIT? A: CB10 breaker finder, CT20 continuity/wire tracer, DV20 non-contact AC voltage detector, batteries, and carrying case per OEM kit datasheet.

Q: CB10 alone vs kit? A: SKU 24338 is CB10 alone; 32848 adds CT20 + DV20 in one case — order the kit only if you need all three functions.

Q: What should I send for a quote? A: Voltage style, kit vs CB10-only, quantity, ship-to. Compatible with systems using Extech CB10-KIT — we do not claim authorized-dealer status.
