Electrical Test — FAQs
Choose according to where you measure: CAT II for appliances, CAT III for distribution inside buildings, CAT IV for service entrances/outdoors. Match the voltage rating too.
Clamp earth is fast and doesn’t need stakes, ideal on bonded systems. 3/4-pole with stakes provides true soil/earth resistance where loops can be opened or on new installs.
Yes — factory or UKAS calibration available for most instruments. Ask our team for options and turnaround.
