(1) Specification of circuit breaker and power cord base on unit’s maximum power (max. current).
(2) Specification of power cord base on the working condition where ambient temperature is 40
℃
(104
℉
) and
multi-core cable with copper conductor(working temperature is 90
℃
(194
℉
), e.g. power cable with YJV
cross-linked copper, insulated PE and PVC sheath) is lying on the surface of slot. If working condition is
different, please adjust the specification according to national standard.
(3) Copper-core cable should be used.
(4) The above sectional area is suitable only for maximum 15m(49-1/5ft.). If exceeds 15m(49-1/5ft.), sectional
area should be scale up to prevent overload current from burning or causing fire hazard.
(5) Specification of circuit breaker base on the working condition where the ambient temperature of circuit
breaker is 40
℃
(104
℉
). If working condition is different, please adjust the specification according to
national standard.
(6) The air switch should include magnetic trip function and thermal trip function so that system can be
protected from short circuit and overload.
(7) An all-pole disconnection switch having a contact separation of at least 3mm(1/8in.) in all poles should be
connected in fixed wiring.
