2.13 Electrical installation requirements
Circuit Breakers (MCB ~ Miniature Circuit Breakers)
For over current protection, a Type ‘D’ circuit breaker (designed specifically for this type of equipment) must be fitted, as a
recommend alternative a higher rated type ‘C’ type breaker can be used (see below). Establishments with standard (Type ‘B’)
circuit breakers are sensitive to ‘surges’ which occur on switching on freezers, refrigerators and other catering equipment,
including microwave combination ovens. An individual, suitably rated over current circuit breaker should be fitted for each
appliance installed, along with a separate dedicated Residual Current Device (Ground Fault Circuit Interrupter).

Residual Current Device (RCD)
The installation regulations require protection by a Residual Current Device (Ground Fault Circuit Interrupter). Suitable residual
current devices, with a high immunity to nuisance tripping, meeting the relevant national regulations must be used. As long
cable runs can be a factor in nuisance tripping, they should be avoided.
If the installation includes more than one appliance, one residual-current (GFCI) device must be provided for each appliance.
Low impedance electrical supply
This commercial combination microwave oven complies with EN 61000-3-11. However, when connecting sensitive equipment
to the same supply as the appliance, the user should determine in consultation with the supply authority, if necessary, that a
low impedance supply is used.
