MARTINDALE ELECTRIC TB118KIT1 Complete Electrical Safety Kit foar Gas Engineers User Manual

Key features

  • Complete electrical safety kits for gas installation and service engineers
  • All in one solution for earth verification, locking off and proving dead
  • Includes voltage indicator, proving unit, locking off devices and earth checker
  • Slimline and miniature push pin MCB lock outs and fused spur locking off device
  • Essential for compliance with Electricity at Work Regulations for safe working and TB118

OInv2e0rv1i8ewGagsoeSsahfeerReegister Technical Bulletin 118 was amended. The changes require new test procedures to keep service engineers safe from electrical hazards. Starting from July 2020 Gas Safe registration will require knowledge and competency in how to safely isolate the electrical supply to appliances.

Martindale TB118KIT1 includes all the essential test tools for gas safety engineers to achieve compliance. The new kit combines easy to use tools for live voltage indication and earth loop verification together with fused spur and MCB locking off devices in a high quality soft carry case.
The full kit compromises of:


  • Four essential locking off devices, LOK10, LOK11, LOK7 for MCBs and LOKFS1 for fused spurs
  • Padlock, pen tag and carry case


  • Voltage indicator and matching proving unit for safe and simple voltage oantsjutting
  • Combination carry case


  • Earth loop resistance and polarity checker for socket and spur testing


  •  Soft carry case with shoulder strap
