We're looking at two different ovens:
One has three phase power and the following electrical specs:
400-415V, 50Hz, 12.5kW, 3P+N+E, 17.4A/hr, 5 wire
And the other is single phase with the following specs:
230-240V, 1P+N+E, 50-60HZ, 4.7kW
Am I right in thinking the three phase oven uses a huge amount of power,
or does the three phase efficiency come into it ?
Thanks !
