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 type A residual current
device (RCD).
•
Fixed wiring appliances incorporate a locally situated switch disconnector to
connect to, 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
