When installing a service, what connection is made first?

When installing a service, the neutral connection is made first to ensure safety throughout the process. Connecting the neutral first allows the system to maintain a reference point for voltage, which is essential for properly balancing the load across the service. This helps in preventing accidental electrical shocks during installation and also ensures that the system is effectively grounded, as the neutral provides a path back to the ground in case of a fault.

Making the neutral connection first also aids in establishing the whole electrical system function correctly, as it connects the service to the grounded components effectively. Once the neutral is established, other connections, such as hot and ground, can be made with a clearer understanding of the electrical flow and potential hazards being minimized. Prioritizing the neutral connection enhances safety and reliability in electrical installation work.
