Fuse calculations for IEC are done according to 60364-4-43 electrical installations of buildings, part 4:
protection for safety- section 43: protection against overcurrent. Fuse sizes are calculated in order to protect
the cable against short circuit.
Fuse
calculations for cUL and UL: The indicated fuse size is the maximum fuse size in order to protect the
motor against short circuit. For cUL fuse HRC form II, for UL fuse class K5
Earthing
The earthing cable connected to the compressor (PE) should be minimum 10 mm
2
(according to EN 60204-1
section 828).
Cable sizing according IEC
The tables below indicate the current carrying capacities of cables for 3 commonly used installation methods,
calculated according to standard 60364-5-52 - electrical installations of buildings part 5 - selection and erection
equipment and section 52 - current carrying capacities in wiring systems.
The allowed currents are valid for PVC insulated cables with three loaded copper conductors (maximum
conductor temperature 70 °C).
Installation method B2 according table B.52.1.
