Single-phase distribution board
Uses one phase and a neutral to supply the loads.
Three-phase distribution board
Uses three phases and usually a neutral, so it can supply larger or three-phase loads.
Why proper distribution is needed
In a three-phase distribution board, single-phase loads must be distributed as balanced as possible across the three phases.
What we check
We measure the currents per phase and check if one phase is significantly more loaded than the others.
