This article series explains how to estimate the electrical service size (or "electrical power" or "service amps") at a building by visual examination of the But we did not like the position of that weather-head, and we considered that water may be entering the SEC. Two 120V lines usually give us a 240V service. In the photo above we see a three wire mast-head: 3 wires means that there are two 120V lines + a power company neutral. "How do I determine the service amperage?" Start by taking a look at the service entry cables outside and at their entry into the electrical panel.Ī quick look can tell us if the property is served by 240V or only a 120V service, even before measuring the gauge or wire thicknesses that we discuss below. Illustration of common electrical wire sizes for both service entry cables and in-building electrical circuits: wire size versus circuit ampacity and fusing requirement. How to determine the size, capacity, or ampacity of electrical service at a building. What is the diameter of thermostat wire, telephone wire, bell wire? What is the diameter of service entry electrical cabling? What are the common diameters of household copper or aluminum electrical wiring? Here we discuss and present a table of electrical wire sizes, ampacity, and fuse or circuit breaker sizes for common residential electrical wiring circuits. Service Entry & Electrical Cable or Wire Sizes vs Amps vs Run Length We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. This article series gives photos and tables of electrical service entry cable sizes, electrical branch circuit wire sizes, bell wire, telephone wire, thermostat wire, and ampacity or fuse/circuit breaker ratings.

We include tables of aluminum or copper wire sizes for long runs of service entry cables. These Tables of Electrical Service Entry Cable Sizes, Electrical Circuit Wire Diameters, Circuit Ampacity, Allowable Voltage Drop, & Wire Size Increase based on Run Length assist in determining the electrical service size or other required electrical wire sizes at buildings. We have no relationship with advertisers, products, or services discussed at this website. Metric wire gauge is 10 times the diameter in millimeters.InspectAPedia tolerates no conflicts of interest. As a number of gauges are in use for various shapes and metals, it is advisable to state the thickness in thousands when specifying in gauge number. The values are stated in closely calculated, approximate decimals of an inch, excluding the metric numbers. The abbreviations signify: AWG = American Wire Gauge, B&S = Brown & Sharpe SWG = Imperial Standard Wire Gauge - (British legal standard). Gages desginations are arranged in columns below.
