Final answer:
The question pertains to the total derating percent for current-carrying conductors in a conduit but lacks detail for a precise answer. The derating factor is influenced by NEC guidelines and factors such as the number of conductors, conduit type, ambient temperature, and insulation. Reference to NEC tables and application of corrections is required for an accurate calculation.
Step-by-step explanation:
The total derating percent of value when current-carrying conductors are installed in a conduit cannot be directly determined from the given statement as it lacks specific information about the number of conductors, the type of conduit, ambient temperature, and other factors that influence the calculation. Derating factors depend on the National Electrical Code (NEC) guidelines that specify the reduction in current-carrying capacity (ampacity) of conductors due to various factors including conductor bundling, high ambient temperatures, and insulation properties.
To find the actual derating percentage, you would need to reference NEC tables and apply them to the specifics of your installation. This typically involves looking up the initial ampacity for the wire gauge and insulation type, then reducing it according to the number of conductors and temperature corrections as provided in the NEC guidelines.
