Electric Service Wire Size Calculator

There are many factors to consider before choosing the proper gauge.

Electric service wire size calculator.

Today we are here with another comprehensive copper and aluminum wire size calculator as we have discussed in detail the topic of how to calculate the proper wire size for electrical wiring. This website provides a wire size calculator voltage drop calculator wire ampacity charts and more. Please don t use this calculator for short service runs. 40 x 1 25 14 3 50 14 3 67 amps.

Allowable voltage drop the calculator allows entry of a voltage drop but caution should be used when doing so to make sure you are calculating the wire sizes in accordance with nec article 210 19 fpn no. Electrical wire size calculator. Southwire s voltage drop calculator is designed for applications using awg and kcmil sizes only. The national electrical codes are the basis of making sure.

Now you can take the advantage of this calculator to do this job j you can also check the classical wire cable size calculator in awg calculating wire cable size formula for single phase circuits. This should be used as a reference only. Wire is sized by the american wire gauge awg system. Common sizes include 14 12 10 8 6 and 2 gauge wire.

The figure we would plug into the calculator would be. The calculations are fairly complex so most electricians use a convenient calculator tool to properly size the main electrical service. The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f. 100 amp service provides enough power for a small home without electric heating.

The purpose of the residential electrical load calculation is to accurately determine the size of the electrical service base upon the electrical equipment that will be installed. Please check with your electrical inspector or a licensed electrician for the proper wire size. Nfpa 70 national electrical code table 310 15 b 16 17. Wire gauge refers the physical size of the wire rated with a numerical designation that runs opposite to the diameter of the conductors in other words the smaller the wire gauge number the larger the wire diameter.

This wire size calculator will calculate the appropriate wire gauge for a circuit based on amps voltage distance and load. When sizing conductors calculations limits wire size to voltage drop and nec ampacity. Introduction to the electrical load calculator. Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run.
