Calculate the nominal resistance of appliance supply cable protective conductors for the purpose of earth continuity testing while PAT testing with this Lead Resistance Calculator from Seaward.

The Lead Resistance Calculator is very useful when testing appliances with supply cables, particularly if they are long, as it will give the PAT Tester the pass/fail limit for Earth Continuity without having to look at a table or manually calculate.

Ideal for PAT testers; this Lead Resistance Calculator calculates 0.1 ohm + R where R is the resistance of the supply cable which is the requirement for appliance safety testing.
