What is the maximum number of bends permitted in RMC between outlet boxes?

The maximum number of bends permitted in rigid metal conduit (RMC) between outlet boxes is typically limited to 360 degrees. This limit is established to ensure that the installation is safe, maintainable, and does not impede the flow of electrical cables. Bends in conduit can potentially make it difficult to pull wires through, increasing the chances of damage to the insulation and making the installation unnecessarily complicated.

The 360-degree allowance means that you can have a total of bends that collectively do not exceed 360 degrees, which is roughly equivalent to three 90-degree bends or a combination of different angles. This regulation helps electrical professionals maintain high standards for conduit installations, promoting safety and reliability in electrical systems.
