2. Power cable selection (general)
When selecting cable specifications, consider the following use
conditions:
<1> Motor rated current or actual current on the machine
<2> Power cable type (heat resistance, etc)
<3> Cable installation environment (ambient temperature, etc.)
<4> Requirement for waterproofness (Pay attention to the matching
diameter with a cable clamp)
<5> Compliance with CE marking (compliance with various safety
standards and EMC standard)
Examples of heavy-duty power cord selection are provided below.
Before applying an example of selection to an actual case, the user
needs to carefully check the use conditions. Note that data such as
power line diameter information is calculated based on JCS No. 168
D (1980) "Allowable Current of Power Cable (No. 1)".
