Remember, proper grounding is crucial for armored cable installations to ensure safety and optimal performance.
Metal-Clad (MC) Cable: The Versatile Champion
Metal-clad (MC) cable shares the protective prowess of its armored counterpart, but with added versatility. Its flexible metal armor, often interlocking or continuously welded, allows for bends and curves, making it ideal for both indoor and outdoor applications. Damp or wet environments? No problem! MC cable thrives in these conditions, shrugging off moisture and corrosion with ease. And for areas with fluctuating temperatures, MC cable remains unfazed, making it a reliable choice for attics, crawlspaces, and even industrial settings.
Taming the Beasts: Installation Tips for Armored & MC Cable
While offering superior protection, armored and MC cables demand specific installation considerations. Working with these heavyweights requires proper tools and practices. For armored cable, grounding lugs are essential for a safe connection. MC cable, on the other hand, necessitates specialized connectors and fittings to maintain its protective integrity. Remember, consulting a qualified electrician for complex installations is always advisable.
