The amp clamp is rated to measure up to how many Amps?

• A. 300 Amps
• B. 600 Amps
• C. 1000 Amps
• D. 200 Amps

Answer: (B)

Amp clamps are designed to give accurate readings only up to a specified maximum current. Beyond that limit the magnetic core can saturate, and the reading stops scaling proportionally with the actual current, which means you lose accuracy.

In this item, the rated maximum corresponds to a mid‑to‑high range that many standard clamps offer. This is a practical balance: it covers the currents you’re most likely to encounter in typical electrical work while still providing good resolution at lower currents. If you needed to measure higher currents reliably, you’d use a clamp with a higher rating; if you only work with smaller currents, a lower rating would work but would limit the maximum you can measure without compromising accuracy.

So the principle is clear: the clamp’s rating is the ceiling for accurate measurement, and the option that sits at that mid-high point is the best match for a broad set of common applications.
