British Standard (BS) 6396 (BS 6396:2008+A1:2015—Electrical systems in office furniture and educational furniture) sets out requirements for ensuring electrical power, data and telecommunications systems in office furniture, office screens and educational furniture are safe.
All electrical equipment must be designed and tested to:
British Standards can be used to demonstrate this. BS 6396 is the relevant standard for electrical systems in office furniture and educational furniture which are connected to the mains via a 13 Amp plug.
Plug sockets installed in office and educational furniture are intended to supply electrical equipment with a fuse rating of no more than 5 Amps. Section 7 of BS 6396 describes the need to test such equipment and sets out the procedures for doing so.
You should carry out these tests on reconfigured desks and screens as well as new installations. You must repeat the tests periodically to fulfil the requirements of BS 6396 and the Electricity at Work Regulations in maintaining a safe working environment.
Meeting the requirements of BS 6396 means following the points listed below when configuring electrical systems. Any electrical system being fed from one 13 Amp BS 1363 UK plug must not have more than:
as shown by the diagrams below.
If you have equipment rated higher than 5 Amps, do not plug it in to your office or educational furniture. The sockets in this furniture are designed for office equipment only. Also, make sure:
BS 6396 was updated in December 2015 with a requirement for all electrical systems within office or educational furniture to include safety protection in the form of a 30 milliamp (mA) residual current device.
An RCD monitors the flow of electricity (measured in Amps) through a circuit.
If the current sent down the live (brown) wire to the electrical appliance does not match the current returned via the neutral (blue) wire, the RCD sees that as a leak in the circuit and automatically stops the flow of electricity.

Although all RCDs do the same job, the speed at which they stop the flow of electricity is determined by the device’s rating, measured in milliamps (mA).
BS 6396 says electrical systems within office or educational furniture should include a 30 mA RCD. This is classified as a high-sensitivity device, capable of stopping the flow of electricity within around 40 milliseconds and preventing irreversible heart damage or death from electric shock.
As little as 0.5 mA can cause injury from electrocution in less than a tenth of a second. Anything over 40 mA is likely to be fatal.
The requirements of BS 6396 do not apply in the following circumstances.
