Socket & See TB118 Advanced Kit

The Socket & See TB118 Advanced Kit is the most complete solution for gas engineers complying with Technical Bulletin 118 – The safe isolation of gas appliances.

Every piece of this kit has been specifically chosen to address each part of TB118. The complete kit comprises of 8 parts, including the uniquely engineered Socket & See DLM PRO.

Check power supply earthing

The Socket & See DLM PRO can carry out the required earth loop impedance test, without tripping the installation’s RCD. A loop impedance test can also be carried out at a fused spur prior to installation, as well as at a mains socket with the included SS130 socket interface adaptor

The DLM PRO also includes basic multi meter function to aid fault finding down to component level.

The simplicity of the DLM PRO is very much favoured by gas engineers compared to other units. Simply turn the dial to the required function to begin the test, there are no buttons to press. Furthermore, functions and terminals are colour coloured for easy operation.

Safe to touch test

Before servicing is carried out on a boiler, a sweep of the casing and any extraneous metal work should be carried out with non-contact voltage indicator to check for any hazardous voltages.

The Socket & See VVD PRO non-contact voltage detector strikes at 50v, and thanks to its CAT IV safety rating, is safe for voltage detection up to 1000V.

Feedback from the VVD PRO is provided both visually (red flashing tip) and physically by vibration.

Lock out and tag out

Supplied in the Advanced Kit are three lock off devices, allowing safe isolation in almost any environment.

  • 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)

The purpose of a lock out device is to prevent the circuit the engineer is working on from becoming accidently reenergised, for example by a customer or colleague. Each lock out device includes two warning tags with space for the engineers name and contact information.

Safe isolation: PROVE – CHECK – PROVE AGAIN

Many are familiar with two pole voltage indicators as a safe and affordable way to check if an appliance is electrically dead. The Socket & See VIP150 voltage indicator is included with the TB118 Advanced Kit.

The VIP150 is simple to use and small enough to access tight spaces and terminal blocks. There are no batteries or buttons to press. Indication of volts present is indicated by bright red LED.

It is most important to check the correct operation of the VIP150 both before and after checking for voltage at the appliance terminals.


The use of a ‘known source’ such as the SP400 proving unit is very important. Having a dedicated known source that is easily accessible saves time and encourages best practices.
