Martindale Electric Ltd Martindale Electric has always been a pioneer in test equipment. Helping electricians and maintenance engineers safely carry out their work since 1928.

Martindale Electric, founded in 1928, has always been a pioneer in test equipment. Martindale Electric also owns the Edgcumbe Instruments Metrohm® products, as well as the John Drummond Engineers range of test lamps. We are a British owned company, based in Watford, just 5 minutes from junction 5 of the M1. Our product range helps electricians and maintenance engineers carry out portable appliance

testing, check fixed wiring for 17th Edition and Part P testing, safely prove dead, and measure everything from light and sound levels to microwave leakage and power consumption. Our firsts include:

The first ever socket tester. The first safety insulation tester. The first self proving non-contact voltage indicator. The first low cost fuse finder. The first non-trip, no battery, no test button loop, tester displaying PE, PN PFC & PSC
The first handheld insulation tester with polarisation index. The first advanced socket tester, as defined by the Health and Safety Executive. The smallest and lightest handheld PAT Tester.

Helping electricians work safely. Today is International Electricians' Day, a day that recognises the contribution electrical professionals make in keeping homes, workplaces, and infrastructure safe and powered.

At Martindale Electric, we're passionate about electrical safety and supporting those who work with electricity every day.

Safe isolation remains one of the most important safety procedures for anyone working on or near electrical systems, helping to reduce risk and prevent accidents. It protects workers and others from the risk of electric shock, burns and other injuries, while ensuring electrical systems remain safe during inspection, maintenance, and repair.

To support electricians and others working with electrical installations, we've put together a practical guide to the Safe Isolation Procedure, covering:

🔸What is the safe isolation procedure?
🔸Key terminology
🔸Why safe isolation procedures are essential
🔸The risks of failing to follow the safe isolation procedure
🔸Essential tools for safe isolation
🔸The correct steps in the safe isolation procedure
🔸Relevant guidance and regulations

Advanced Proving Units – designed for safer working. As electrical workers encounter more DC systems across renewables, solar installations, battery storage, and EV charging, the need for DC-compatible proving and testing devices is increasing.

Safe isolation procedures remain essential when working on or near electrical systems, and the Electricity at Work Regulations require circuits to be proved dead before work begins - with voltage indicators verified before and after testing.

The article highlights how advanced AC/DC proving units are helping support safer working practices by offering:

🔸Future proofing with selectable AC & DC outputs
🔸Stepped voltage ranges matched to two-pole tester thresholds
🔸Support for high and low impedance indicators, test lamps and meters
🔸Why proving units are safer than using a live source

Incorporating proving devices into electrical safety processes can improve reliability and help reduce the risk of electrical accidents.
