Selecting the Right Multifunction Tester for Electrical Work
Multifunction testers (MFTs) are indispensable tools for electricians, ensuring the safety and compliance of electrical installations. Many MFT options exist in the UK, tailored to diverse electrical work scopes.
Key Considerations
Budget and Quality: Typically, the price of an MFT aligns with its quality and features. Premium models often boast superior accuracy and comprehensive features, whereas lower-priced alternatives may lack certain functionalities or necessitate costly upgrades.
Specific Needs: Tailoring your MFT choice to match the nature of your electrical work is paramount. For instance, domestic electricians adhering to Part P regulations might not require advanced capabilities like 400V line testing or phase rotation industrial-type RCD testing.
Test Requirements: Complying with BS7671 mandates 7 tests to scrutinise electrical installations. However, depending on the project scope, only a subset of these tests may be necessary, streamlining your MFT requirements to focus on essential functionalities.
