Before commencing work on any appliance that is connected to an electrical supply it is essential to test that the appliance itself and any metal piping or tabling that is connected to it is tested to ensure that it is not live due to an electrical fault. Indeed, due to several fatalities over the years, it has become custom and practice within the gas industry to use a single-pole or no-contact live-circuit detectors (sometimes referred to as Voltage Sticks).

Whilst European plugs do have an earth connection, this is in the form of a metal strip within the body of the plug which only connects the earth when the plug is connected to a matching socket which has an internal earth terminal that connects with the strip connector in the plug. See picture below. This means that when connected using a travel adaptor of the type shown in this case, the appliance is not earthed.

We understand that some service engineers claim to have been advised by trainers to use a voltage stick to “test for dead” as part of a “safe isolation procedure” (see ceda Guidance document No 37). In the opinion of the ceda Technical Support Group, this is not only bad practice but potentially dangerous.
