The example oven, should be connected at 400 V by a cable
with a 25 mm
2
section (minimum) for each phase and 16mm
2
(minimum) for earth.
Modular ovens incorporate an energy-saving device which dis-
tributes power between the modules thereby reducing electri-
city consumption. Depending on configuration, a four-module
oven can be made to work with the same amount of power
required for a two or three-module oven.
If the configuration is for three modules, the total electricity
consumption will be the sum of the three most powerful mo-
dules. In these cases, the cable sections are calculated using
the new total.
For example, the total consumption of an “E” oven formed by
2 decks of 20 cm height + 1 decks of 30 cm height with steam
Generator + 1 Pizza decks + 1 Proofer connected at 400 V.
