ElectricalRepair and Maintenance Decisions2MildApprentice Electrician
Apprentice electrician is confused about the correct resistance calculation for PAT testing extension leads because the IET guideline adds 0.1 ohms but his logical reasoning suggests only the cable resistance matters.
Existing guidelines are unclear about why 0.1 ohms is added for extension leads with no equipment, causing confusion for trainees.
