Socket & See TB118 Essential Kit

The Socket & See TB118 Essential Kit is an affordable entry level kit to help gas engineers comply with TB118. It contains everything an engineer needs to carry out an earth loop impedance and safe to touch test, as well as safe isolation, lock off and proving and appliance is electrically dead.

Earth fault loop impedance testing

The Socket & See PDL234+ checks earth fault loop impedance. This unit may look familiar to some ex British Gas engineers, as it has been a tool box staple for many years.

The PDL234+ is a simple GO / NO GO tester with clear LED indication. As opposed to an exact reading (like with the DLM PRO), the PDL234+ indicates the range that the measured value falls between. These ranges are…

  • < 1 (Ω) – Green LED indication
  • < 2 (Ω) – Green LED indication
  • < 100 (Ω) – Green LED indication
  • < 200 (Ω) – Green LED indication
  • > 200 (Ω) – Red LED indication

The PDL234+ is exceptionally easy to use with no dials and just one button. Simply plug in and test. The PDL234 also checks correct socket wiring as well as mains voltage.

Safe to touch test

What is a safe to touch test? This test checks for any hazardous voltages of 50V or above that may be present on the boiler casing or any extraneous metal work.

A simple sweep of the casing and metal work with the CAT IV rated Socket & See VVD PRO provides the engineer with physical (vibration) and visual warning of any voltage present between 50 – 1000V). If no indication is given, then the engineer can assume the casing is safe to touch.

REMEMBER – Your non- contact voltage detector must be proved on a KNOWN SOURCE before and after use.

Safe isolation – Lock Out Tag Out

TB118 ensures the engineer is working as safely as possible, regarding the safe electrical isolation of gas appliances. A part of this is ensuring the appliance is electrically dead before work is carried out.

Using the Socket & See VIP200 voltage indicator, the user can check for voltages between E-L / N-L and E-N.

The correct operation of the VIP200 must be proved on a known source before and after operation. The Socket & See SP200 is included with this kit for this purpose.


The VIP200 also features handy phase indication and audible continuity functions, as well as a bright LED torch.

To prevent the electrical supply to the boiler from inadvertently being turn on, this kit includes three lock off devices.

  • MCB LOCK – For locking off directly at the MCB
  • FUSE LOCJ – For locking off all types of fused spur
  • PLUG LOCK – For locking off 13A 3 pin plug (UK)

Each lock out device includes two warning tags which include space for the engineer’s details.
