Which requirement must be met for a branch circuit supplying an isolated grounding receptacle in a general care space?

The requirement for a branch circuit supplying an isolated grounding receptacle in a general care space mandates that it shall have green insulation with yellow stripes. This color-coding is crucial as it serves to visually identify circuits that are specifically designed for isolated grounding. The distinctive green insulation with yellow stripes is a standardized practice that helps personnel recognize circuits that are meant to maintain electrical isolation and minimize the risk of ground faults, which is essential in medical and care environments.

This visual indicator aids in ensuring that anyone working with the circuit can quickly understand its specific application and safety measures, contributing to a safe and compliant electrical installation in sensitive areas like healthcare settings.
