Nec Bundling Conductors. When multiple conductors are bundled together, heat. the nec provides minimum size requirements for conductors to prevent overheating and fire. Bundling more than three conductors in the same raceway degrades the ability of each conductor to dissipate heat, requiring you to adjust the ampacity downward, accordingly. in general, you can use only conductors contained in tables 310.104(a), except where otherwise permitted in the nec (an. Insulation type, ambient temperature, and conductor bundling are three primary factors in determining how big a conductor has to be for it to safely carry the current imposed on it. the national electrical code requirements for conductor sizing and overcurrent protection have always been confusing and complex. the nec allos you to bundle conductors as long as it doesn’t exceed 10ft or 10 % of the entire run(310.15a2ex). apply adjustment factors for bundled conductors: Here’s the conductor bundling adjustment formula:
