The Earth Bond Test
- Checks the connection on the earth wire from the pin of the plug to the bodywork of the appliance
- The PAT Tester gives a resistance reading, this resistance reading indicates how good the connection to earh is.
- For appliances the pass value is normally (0.1 + RΩ) where R is the cable resistance.
- If a reading is less than 0.1Ω the result is PASS
Cable Resistance Calculator
This calculator is designed to assist testers to find the pass value for an appliance fitted with a cable length up to 50m and a CSA (Cross Sectional Area) of 2.5mm²
Please note if you use this calculator to calculate the resistance of a power lead on its own then you need to deduct 0.1Ω
