PRODUCT REAL SHOT
500kcmil 600V Interlocked Aluminum MC Cable:Heavy-Duty Power Delivery for Large-Scale Indoor Installations
This 500kcmil 600V metal-clad cable is constructed with interlocked aluminum armor, a separator tape, and THHN/THWN-2 insulated conductors. It is specifically designed for building wiring, equipment connection, industrial installation, and indoor power distribution where high current capacity is required. Typical applications include main feeders from transformers to switchgear, large motor supplies, and heavy industrial branch circuits. The interlocked aluminum armor provides outstanding mechanical protection against crushing and pulling while remaining manageable for field bending. THHN/THWN-2 conductors are rated 90°C dry and 75°C wet, with a nylon jacket that resists oil and abrasion. Two relevant keywords for this product are high-ampacity MC cable and main feeder armored cable. A separator tape ensures electrical isolation between conductors and the armor. Certified to UL 1569 (Metal-Clad Cable) and UL 83 (Thermoplastic-Insulated Wires), this 500kcmil cable is the backbone of large-scale commercial and industrial power systems.

FAQ
What is the typical bend radius for 500kcmil MC cable during installation?
Minimum bending radius is approximately 7 to 8 times the cable diameter due to the large conductor size. Use proper bending tools.
How do I terminate such a large gauge cable?
Use compression lugs or mechanical lugs rated for 500kcmil. Ensure the termination is matched to the conductor material (copper).
What voltage drop should I expect over long runs?
For a 500kcmil copper cable at 300A load, voltage drop is about 1.5V per 100 feet at 480V. Calculate based on your actual load and distance.
Does this cable require special supports in cable trays?
Yes. Follow NEC support spacing for large cables – typically every 3 to 4 feet for horizontal runs due to the weight.
