Current clamps for measuring AC and DC current
With a current clamp you measure the current in a conductor without breaking the circuit: you simply clamp the jaws around the cable. For electricians, maintenance technicians and installers, that is the fastest way to check load, trace faults or run through a distribution board without unscrewing anything. Simple models measure alternating current, while more capable clamps handle both AC and DC and also read voltage, resistance and frequency.
For hard-to-reach bundles there are flexible measuring loops you wrap around thick or multiple cables. When choosing, look at the measuring range in amperes, the accuracy and the safety category that matches the voltage you work on. Brands such as Fluke and Facom are known for reliable readings and rugged housings that survive a drop on the shop floor.
Pick a current clamp that suits the currents you measure day to day, so your readings stay repeatable and safe. A good current clamp saves time on every fault-finding job and keeps you working hands-free at the panel.
