How far must conduit be clamped from the service box?

1 ft

2 ft

3 ft

The requirement for how far conduit must be clamped from the service box is based on safety and code compliance to ensure secure installation and minimize the risk of damage or disconnection. Clamping conduit within a specified distance from the service box helps prevent mechanical stress or movement, which could occur as connections and wiring are handled.

In this case, the correct answer indicates that conduit must be clamped no more than 3 feet from the service box. This distance is specified to ensure that the conduit remains adequately supported and in compliance with the National Electrical Code (NEC) guidelines. Proper support and installation not only promote safety but also facilitate easier maintenance and troubleshooting in the future. This understanding supports the importance of following electrical codes for reliable and safe electrical installations.
