The AEMC Model NC-1 is a compact non-contact AC voltage detector designed for quick and safe verification of voltage presence in electrical circuits. With voltage sensitivity from 100 to 240V AC at 50/60Hz, it is suitable for standard residential and commercial electrical applications .

The detector has a detection distance of less than 5mm, allowing users to identify live circuits without making physical contact with conductors. It is rated for overvoltage CAT III 600V with Pollution Degree 2, making it suitable for indoor use in accordance with international safety standards .

Powered by two 1.5V AAA batteries, the NC-1 is always ready for use when needed. Its compact size fits easily in a pocket or tool bag, making it convenient for electricians, maintenance technicians, and homeowners to carry for routine voltage checks .

Applications include verifying circuit deactivation before working on electrical systems, identifying live wires in junction boxes and outlets, and troubleshooting electrical circuits in residential and commercial buildings. The simple operation requires no special training—just touch the tip near the conductor and observe the indication .
