What is meant by "service entry" in electrical installations?

In the context of electrical installations, "service entry" refers specifically to the point where the electrical supply enters a building or structure, making it the critical juncture for delivering electricity to the internal distribution system. This point is vital for ensuring that the electricity is safely routed through the building's circuits and that all electrical installations comply with local codes and regulations.

Understanding the service entry is essential for various reasons. It is typically where the utility company's service line connects to the building’s electrical panel and where meters may be located to measure electricity consumption. Additionally, proper installation and maintenance of this entry point are crucial for safety, as it ensures that the incoming electrical supply is adequately protected against faults and surges.

While other options highlight important concepts within electrical installations, they do not define "service entry." The installation of devices, connections for renewable energy sources, and grounding points all serve distinct roles within an electrical system but do not pertain to the specific function of service entry.
