Stop Making These Mistakes - Insulation Resistance Testing

In this video, we carry out an Insulation Resistance Test on a brand-new electrical installation using a multifunction tester. You'll learn: ⚡ How to set your tester to the correct megohm (MΩ) range ⚡ Why we use 500V DC for insulation resistance testing ⚡ The minimum values required by the On-Site Guide and Guidance Note 3 ⚡ How to prove your test leads are in good condition before testing ⚡ Why lamps, loads and electronic devices must be disconnected ⚡ The importance of leaving switches ON in the circuit but protective devices OFF ⚡ Why the earthing and bonding conductors must be connected during testing ⚡ How to perform the three required insulation resistance tests: We also discuss how to interpret high insulation resistance readings, what a reading of +999 MΩ means, and why we would expect very high readings on a new installation. Whether you're studying for your electrical qualifications, preparing for practical assessments, or refreshing your testing knowledge, this video walks through the process step-by-step. 🔔 Subscribe for more free electrical training videos https://youtube.com/c/GSHElectrical?s... == 🕐 Time Stamps - Cut to the action 🕕 == 00:00 - Insulation resistance test 00:19 - What voltage 01:09 - Per checks 02:15 - Must be in place 02:50 - Electronic components 03:19 - Earthing and bonding 04:11 - Helpful image 04:40 - Carrying out the test 🔵 Do YOU Know What Happens to a Circuits Insulation Resistance When the Circuit Length is Increased?    • Do YOU Know What Happens to a Circuits Ins...   Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2, 3 plus AM2, AM2S and AM2E.
