How should conduits be modified if they need to carry more circuits than initially designed?

Increasing the size of the conduit or adding extra conduits is the appropriate approach when a conduit needs to carry more circuits than it was initially designed for. This modification allows for sufficient space for additional wiring while maintaining compliance with safety codes and regulations.

When conduits are designed, they have specific fill capacity limits determined by the size of the conduit and the number of wires it can accommodate. If the demand for more circuits arises, simply increasing the diameter of the existing conduit permits a greater volume for wiring, reducing heat buildup and ensuring that electrical performance is not compromised.

Another effective method is adding extra conduits which can segregate circuits for better organization and safer management of electrical pathways. This approach is crucial in preventing overcrowding within a single conduit, which can lead to overheating and potential hazards.

In contrast, using a smaller conduit would not sustain additional circuits and could lead to safety issues. Removing existing circuits defeats the purpose of expanding capacity. Moreover, conduits are generally designed to be adjustable and flexible to accommodate changes in electrical needs, so the notion that they cannot be modified is inaccurate.
