What is MC cable?
MC Cable Definition
MC Cable, by most common definition, is a factory assembly of one or more insulated circuit conductors enclosed in an armor of interlocking metal tape or a smooth or corrugated metal sheath.
How do you secure a MC cable?
Type MC cable must be supported and secured by staples, cable ties, straps, hangers, or similar fittings, designed and installed so as not to damage the cable. Type MC cable, with four or less conductors sized no larger than 10 AWG, must be secured within 12 in.

Is MC cable better than Romex?
Safety: Compared to Romex, MC cable is safer to install due to its metallic sheath. This sheath helps protect against accidental shearing and penetration, reducing the risk for accidental wire exposure. Romex sheathing is easily penetrated or sheared, making it less safe unless run through protective conduit.
What is better Romex or conduit?
Conduit has one big advantage over ROMEX® wiring and that is flexibility. While ROMEX® is available in a number of sizes, the insulated wires are all white, black and red. Using conduit, it is possible to use any color wire and implement color coding schemes not possible with ROMEX®.
Why is Romex so high?
These price increases are due to factors such as China’s economic recovery from the pandemic, sustainable green energy stimuluses, and supply disruptions. China’s rising industrial production along with aggressive sustainable energy initiatives accredits the country to being the highest consumer of copper in the world.

Should electrical wires be in conduit?
9 Answers from MyBuilder Electricians
All cables should either be contained in steel conduit or protected by 30mA RCD. If these two cannot be met, then the cables should be installed at least 50mm (2″) from the surface.
