Electrical installation requirements
Circuit Breakers (MCB ~ Miniature Circuit Breakers)
For overcurrent 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, refrigerato
rs and other catering equipment,
including microwave combination ovens. An individual, suitably rated overcurrent 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.

UK 13A models are fitted with a moulded plug to BS1363,
fused at 13A.
EU 16A models are fitted with a moulded plug to CEE 7/7
(Type F Schuko) rated at 16A
30A models are fitted with a blue 32A plug to IEC 60309 (EN
60309).
Connected to a dedicated RCD (GFCI) protected supply, with
appropriate circuit breaker as detailed above.

Twin phase models should be connected as shown (the twin
phase oven requires a three phase supply, utilising L1 & L2 as
two separate single phases, L3 is not used).

Single phase models, utilising L1 & L2 split phase supply
(240V) or L1 & L2 from a three phase supply (208V). Neutral is
not used.
15A models are fitted with HBL5666C NEMA 6-15P & 15A
HBL4570C NEMA L6-15P plugs.
20A models are fitted with a HBL5466C NEMA 6-20P plug.
30A models are fitted with YP-91L NEMA 6-30P & HBL2621
NEMA L6-30P plugs.
Connected to a dedicated RCD (GFCI) protected supply, with
