The depth of working space, which you measure from the enclosure front (not the live parts), cannot be less than the distances in Table 110. These distances are determined by voltage-to-ground and three different conditions: Condition 1. Exposed live parts on one side of the working. The neutral conductor is always a grounded conductor, but a grounded conductor is not always a neutral conductor. Most people refer to all grounded (white) conductors in branch circuits in a dwelling as neutral. The circuit breakers in your electrical panel are grounded to make them safer in the event that something goes wrong. When an electrical panel isn't grounded, how can you tell what you should do? If the power outlets have two prongs instead of three, you can tell if the building is grounded. Whether you're a new DIY homeowner or tackling your first electrical repair, understanding grounding rules is essential for both safety and code.
