Is it permissible to splice or tap wires inside a conduit body?

Splicing or tapping wires inside a conduit body is permissible only if the conduit body is rated and sized properly for that purpose. This is in accordance with the National Electrical Code (NEC) guidelines, which specify that conduit bodies must be appropriately selected based on their intended use.

A conduit body that is not rated or properly sized may not provide adequate space for the wires, which could lead to overheating and potentially create a fire hazard. Ensuring that the conduit body is sized correctly is essential to maintain the required bending radius and to accommodate wire fill requirements, allowing for safe and efficient operation of the electrical system.

Thus, it's not just a matter of whether splicing or tapping is allowed; it's crucial that the equipment used meets specific criteria to ensure both safety and compliance with electrical codes.
