SWITCH OFF ELECTRICITY AT THE MAINS BEFORE WORKING ON EXISTING CIRCUITS
All modern kitchen appliances come pre-fitted with a plug ready to use.
If you required the plug to be hidden e.g. under a work surface, then a fused
connection unit can be fitted above the work surface with the cable running to a new
socket under the work surface. To hide the plug fit a fused
connection unit above the work surface (see Fitting a fused connection unit)
and then run 2.5mm2 cable from the fused connection unit to a new socket
underneath the work surface (see Fitting a new power socket).
The appliance can then be plugged in there.
