Requirements for the connecting cable Tab. 2-12
NEC
Cable ■ Copper cable, four-core (L1, L2, L3, PE).
■ THHN copper or equivalent is recommended (2000 V test voltage) designed
for a maximum temperature of 90° C (194° F).
■
No aluminum cables may be used to connect the machine.
Cable cross-section ■ The cable cross-section must comply with NEC 670-4 (a). The cable cross-
section must be designed for at least 125 % of the nominal current. The
nominal current is specified on the nameplate.
■ To ensure voltage stability and rating, the line dimension should be larger
than specified in the NEC table 310-16.
Requirements for the connecting cable Tab. 2-13
4.2 Power supply
Residual current device (RCD)
Notes
■ Whether a residual current circuit breaker has to be used
depends upon the local electricity company.
■ On the line side, only residual current circuit breakers of type
B (sensitive to all types of fault current, EN 50178/5.2.11.2;
VDE 0160) are approved.
A residual current circuit breaker provides protection from fault
currents due to directly or indirectly touching live parts.
