Electrical Wire Heat Rating at Catalina Holgate blog

Electrical Wire Heat Rating. This circuit must be wired with a conductor that has an insulation rating of at least 75°c (due to the circuit breaker) and sized based on the ampacity of 60°c (due to the receptacle). Specifically, wires get hot because of \$i^2r\$ losses, which is to say the power the wire uses to produce heat, \$p\$, is equal to current squared(\$i^2\$) times resistance (\$r\$). High temperature wires are for applications where temperatures exceed 150 degrees celsius in normal use. For electrical equipment rated for 600 v and less, terminations are typically rated at 60°c, 75°c or 60/75°c. No distribution or utilization equipment. Conductors carry a specific temperature rating based on the type of insulation used on the conductor. For example a 2kg copper wire with 150w dissipated as heat electrical power on the wire, will rise above ambient temperature δτ=50°c in 256 s. Common insulation types can be found. The benefit of a cable with a higher rating is that cables of the same size can carry more current. The three most common conductor temperature ratings are 60ºc, 75ºc, and 90ºc. The minimum cold bend rating for wire is usually defined as the lowest temperature at which it can be bent without cracking under specific laboratory. The consumed power in your wire is p=i^2xr.
