What is aluminum MC cable?
Aluminum MC cable, or aluminum metal clad cable, is an electrical wire used under high ambient temperature in power distribution, particularly in feeder, branch, and service ones, in diverse purpose buildings.
How many amps can you put on number for aluminum?

What is 12 2 MC rated?
12-2C Metal Clad (MC) Cable with Ground, Aluminum Armored, Solid Copper Conductors. Applications: Metal Clad Cable may be used for branch, feeder and service for distribution in commercial, industrial, and multi-residential construction.
What is MC cable rated for?
MC Cable can be used in places of assembly of 100 people or more, such as studios and theaters. Voltage ratings should not exceed 600V in any application.
What is MC Lite cable?
MC Lite is a traditional Type MC cable containing one or more copper grounding conductors; the armor is not an equipment grounding means. Aluminum armored cables are RoHS Compliant. Made in USA of US and/or imported materials.
What size aluminum wire is good for 400 amps?
The right 400 amp wire size requires an aluminum wire size of 1000 kcmil. In contrast, a copper 600 kcmil can handle that amount of power.

Can MC cable be exposed?
Section 330.15 states: Exposed runs of cable, except as provided in 300.11(A), shall closely follow the surface of the building finish or running boards. Exposed runs shall also be permitted to be installed on the underside of joists where supported at each joist and located so as not to be subject to physical damage.
What is ampacity of wire?
Wire Size & Amp Ratings Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Current is measured in amperes or “amps.” You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating.
How can I determine the ampacity of conductors in Conduit?
Please consult a qualified electrician or professional engineer to determine the appropriate values for your specific application. Our new Ampacity Calculator app can help determine the ampacity of conductors in conduit, cable, or directly buried wires. Cerrowire markets through a number of quality retailers and manufacturer’s representatives.
What is the ampacity of a single insulated conductor in free air?
Table 310.15 (B) (17) (formerly Table 310.17) Allowable Ampacities of Single-Insulated Conductors Rated Up to and Including 2000 Volts in Free Air, Based on Ambient Temperature of 30°C (86°F)* [See Table 310.104 (A).] *Refer to 310.15 (B) (2) for the ampacity correction factors where the ambient temperature is other than 30°C (86°F).
What determines the ampacity of an electrical circuit?
The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. Usually, a general-purpose house circuit is designed for 20 amps. Lighting circuits may be designed for only 15 amps.
