IEC 60309 - 3 phase AC sockets
The industrial sockets for AC powering – based on IEC 60309. The typical household rating is 16Amp and 32Amp. With „C and D grade” of circuit-breakers, it may be possible to drain some 18 and 34 Amps from these sockets. It is also possible to take just one phase out from the 3 phase socket and thus get up to 230V/34Amp power supply. This way it maybe possible to supply energy to high power chargers for DC applications.
Based on standard electrician and installation codes, equipment with 4kW and more should have a fixed cable installation.
