(1) AC contactor is used to connect cables with a c.s.a. > 4m2 and up to 10 m2, it is essential to use special connectors, sold in bags of 100(reference: CYC 1-96180).
(2) If cable ends are used, choose the next size down (example; for 2.5 m2, use 1.5 m2) and square crimp the cable ends using a special tool.
