Fits outlet and branch-circuit checks where you need an Extech CT70—selectable 12/15/20 A loads, voltage drop and impedance, plus GFCI (6–9 mA) and EPD (30–37 mA) trip tests.
Key advantages
- Loads — Selectable 12 A / 15 A / 20 A
- Line voltage — 100–250 VAC; ±(1.0% + 0.2 V)
- Voltage drop — 0.1–99.9%
- GFCI / EPD — 6–9 mA GFCI; 30–37 mA EPD
- Wiring checks — Hot/neutral/ground impedance; reverse/open wiring
Typical applications
- Receptacle load capability checks.
- GFCI trip verification.
- False-ground / high N-G voltage troubleshooting.
Selection guide
- Spare CT70-AC cord
- Crew quantity
- North American 3-prong use
Common mistakes
- Using on UPS / dimmer / square-wave outputs.
- Back-to-back load tests without cool-down.
- Treating as a clamp meter substitute.
When to RFQ / what to tell us
- Quantity, spare cords.
- Ship-to.
