Under at least 2 inches of concrete beneath a structure. A conductor is “outside a building” when installed : 230 provides specific criteria, thus solving the problem. For example, is a conductor inside a building if it's under the bottom floor of that building?įortunately, Art. The problem here is that the distinction between inside and outside is sometimes not clear. OutsideĪrticle 230 requirements for a conductor that is inside differ from those for one that's outside. Keep in mind that service-entrance conductors may be either overhead (with a service drop) or underground (with a service lateral). Article 100 tells us that service conductors run from the service point to the service disconnecting means (service equipment - not meter). To understand where service conductors begin, it's important to know that the “service point” is the point of connection between the premise wiring and utility supply conductors. Examples of feeder conductors include conductors supplied from a battery, photovoltaic system, or generator. Conductors and equipment on the load side of service equipment are feeder conductors, covered by Articles 215 and 225 - not Art. To identify a service conductor, first determine whether the distribution point you're working with is on the line side (service) or load side (premises). What you decide here will determine how you do the rest of the job.

To avoid problems, start a service installation by deciding which conductors are part of the service. For example, service conductors for one structure can't pass through the interior of another. Now it's time to focus on installation requirements for service conductors and equipment.Ĭompared to other conductor requirements, those for service conductors can seem unduly restrictive. Starting with general requirements, the article tackled service equipment details and moved into discussions on multiple disconnects and service overcurrent protection.

Part 1 of this two-part series, which ran in last month's August issue, explored how to ensure your service entrance equipment meets Code.
