How many current carrying conductors can you have in a conduit before you have to start derating amparage?

The number of current-carrying conductors allowed in a conduit before derating is specified by the National Electrical Code (NEC). Generally, if you have more than three conductors in a conduit, you need to start derating the ampacity of the conductors. Specifically, for more than three conductors, the ampacity of each conductor must be reduced based on the number of conductors present. For example, with 4 to 6 conductors, the ampacity is typically reduced to 80%, and with 7 to 9 conductors, it’s reduced to 70%.

Yes, but they're not 'phase' conductors, they're 'line' conductors.


How do you check ampere draw?

Best way is to use a clamp on amp meter. You need to be able to put the clamp over a single conductor. This is usually easy to do in the electric panel, but for a device you need to split the conductors. You can take an extension cord you don't need and separate the conductors so you can get the clamp on a single conductor.


Conductors around the house?

Common conductors found around the house include copper wiring in electrical outlets, metal pots and pans for cooking, and metal doorknobs. These materials allow electricity or heat to flow easily through them.


If ther are more than conductors in the raceway the ampacity of the conductors must be derated?

Ampacity must be derated depending on the number of conductors and the ambient temperature. In the Canadian Electrical Code Table 5C denotes derating for the number of conductors. 1-3 conductors = 100% load 4-6 conductors = 80% 7-24 conductors = 70% 25-42 conductors = 60% 43 or more conductors = 50%
