Well, what is the aggregate power consumption of:

  • the big PLC panel?
  • the lighting?
  • all other loads?

Watts = Amps x Volts.

1 Watt = 1 Joule per second.

Effectively all the power (in Watts) going into the panel is dissipated as heat. If you have external devices (motors etc) driven directly from the panel, the power to these can be deducted.

Just take the power (as calculated above) consumed by everything inside the control room.
