Pat testing IEC leads

Hi
Testing earth resistance for a 13A IEC lead. Is tha pass limit still 0.1Ohm + the resistance of the conductor?

thanks

If you are testing the lead separately then 0.10 ohm is not relevant (this is the limit for the connected appliance). Your earth bond reading is relevant to the cord csa and it's length.

Thanks for the reply

Ok yea it makes sense but wouldn't you allow some resistance for the resistance of the 13A plug and socket contacts? Especially as they can be quite flimsy being just 2 blades pushing on the earth prong.

No.
