ELECTRICAL SAFETY AND ADVICE REGARDING
SUPPLEMENTARY ELECTRICAL PROTECTION
Commercial kitchens and foodservice areas are environments where electrical appliances
may be located close to liquids,or operate in and around damp conditions or where restricted
movement for installation and service is evident.
The installation and periodic inspection of the appliance should only be undertaken by a
qualified, skilled and competent electrician; and connected to the correct power supply
suitable for the load as stipulated by the appliance data label.
The electrical installation and connections should meet the necessary requirements to the
local electrical wiring regulations and any electrical safety guidelines.
We recommend:-
•Supplementary electrical protection with the use of a residual current device (RCD). If an
RCD is installed, it must be a type B or B+ with minimum 30mA fault current.
•Fixed wiring appliances incorporate a locally situated switch disconnector to connect,
which is easily accessible for switching off and safe isolation purposes. The switch
disconnector must meet the specification requirements of IEC 60947.
Your attention is drawn to:-
BS 7671:2018–Guidance Note 8 - 8.13 : Other locations of increased risk
It is recognized that there may be locations of increased risk of electric shock other than
those specifically addressed in Part 7 of BS 7671. Examples of such locations could include
laundries where there are washing and drying machines in close proximity and water is
present, and commercial kitchens with stainless steel units, where once again, water is
present.
Where because of the perception of additional risks being likely, the installation designer
decides that an installation or location warrants further protective measures, the options
available include:
•Automatic Disconnection of Supply (ADS) by means of a residual current device having
a residual operating current not exceeding 30mA;
•Supplementary protective equipotential bonding; and
•Reduction of maximum fault clearance time.
The provision of RCDs and supplementary bonding must be specified by the host
organization’s appointed installation designer or electrical contractor and installed by a
suitably qualified and competent electrician so as to comply with Regulations 419.2 and
544.2
