Single Phase, 12A supply protected by either a fuse or a MCB (Minature Circuit Breaker) C type. Do not use an RCD protected supply. (Due to the Motor Drive design, there are high inrush currents which would trip RCD Breakers)

Type B MCBs react quickly to overloads, and are set to trip when the current passing through them is between 3 and 4.5 times the normal full load current. They are suitable for protecting incandescent lighting and socket-outlet circuits in domestic and commercial environments, where there is little risk of surges that could cause the MCB to trip.

Type C MCBs react more slowly, and are recommended for applications involving inductive loads with high inrush currents, such as fluorescent lighting installations. Type C MCBs are set to trip at between 5 and 10 times the normal full load current.

Type D MCBs are slower still, and are set to trip at between 10 and 20 times the normal full load current. They are recommended only for circuits with very high inrush currents, such as those feeding transformers and welding machines

The Vertical Router has AC servo drives fitted. These have high inrush and will trip an RCD breaker.

To connect a Vertical router the supply must not be RCD protected.

A 13A C Type MCB must be used.
