The requirement for isolating devices for solar photovoltaic systems to be installed within 10 feet of the equipment is grounded in safety and accessibility standards. This distance ensures that the isolating device can be easily accessed in an emergency situation, allowing for quick disconnection of power. Additionally, situating the device within this range reduces the risk of electrical hazards by ensuring that maintenance personnel can safely work on the solar photovoltaic system without having to traverse long distances, which could place them in danger.

This proximity not only aids in the effectiveness of operational procedures but also plays a critical role in compliance with regulations and electrical codes designed to enhance safety and reliability in solar energy systems. Being too far from the equipment could hinder rapid responses to issues, making the installation of isolating devices within 10 feet essential for optimal safety and operational efficiency.
