Rated voltage range of MC cable
The rated voltage of MC cable is usually 600V, which means it can be safely used in systems that do not exceed 600V. For example, in common residential and commercial power distribution systems, MC cables can be used for 120V, 208V, 240V, 277V, and 480V lines. However, in specific application scenarios, the voltage level of the cable also needs to be selected based on other parameters such as insulation type and environmental factors.

Installation precautions for MC cables
When installing MC cables, it is necessary to follow NEC specifications and consider the following factors:
Environmental conditions: MC cables can be used in dry, humid, or outdoor environments, but if exposed to harsh conditions, it is recommended to use MC cables with sheaths.
Bending radius: During installation, excessive bending should be avoided to avoid damaging the internal insulation layer of the cable.
Grounding requirements: The metal sheath of MC cable can be used for grounding, but in some applications, additional grounding conductors are still required.
Load calculation: Select the appropriate wire gauge based on the current load to avoid overloading and heating.
