Electrical or Electric is a term that means relating to electricity i.e. the set of physical phenomena associated with the presence and flow of electric charge.  The calculators and data items in this category are provided to assist those working on electrical system such as the wiring of a home.  For more scientific information, go to the category of Electrical Engineering or Electricity

Electrician Estimation Calculators

Installation Time Estimates

• EMT Conduit Installation Time: Estimate installation time of Electrical Metallic Tubing conduit based on the length of conduit, size of conduit and level of difficulty.
• GRC Conduit Installation Time: Estimate installation time of Galvanized Rigid Conduit based on length of conduit, size of conduit and level of difficulty.
• PVC 40 Conduit Installation Time: Estimate installation time of PVC Schedule 40 conduit based on length of conduit. size of the conduit and level of difficulty.
• Metal Clad Cable Installation Time: Estimate installation time of Metal Clad Cable based on length of conduit. size of the conduit and level of difficulty.
• Lamp Lay-in Fixture Installation Time: Estimate the installation time for lamp lay-in fixtures based on size of the fixtures, level of difficulty and number of fixtures.
• 20A Duplex Outlet Installation Time: Estimate the installation time for 20 Amp Duplex Outlets based on the level of difficulty and number of outlets.

Conduit Weight Estimates

• EMT Conduit Weight: Estimate the weight of Electrical Metallic Tubing based on the size of the tubing and the length.
• GRC Conduit Weight: Estimate the weight of Galvanized Rigid Conduit based on the size and length of the conduit.
• PVC Schedule 40 Weight: Estimate the weight of Schedule 40 PVC based on the size, length and whether it is PVC or CPVC.
• Metal Clad Cable Weight: Estimate the weight of metal clad cable based on the size and the length.

Wiring and Box Estimates

• Outlets and Wiring for a Room: Computes the number of outlets (boxes) and length of wire to connect them in a room based on the room dimensions and the outlet spacing.

Electrician Calculators

• Voltage Drop: This computes the voltage drop in volts and as a percentage over a length of cable (wire) based on length of wire, gauge, wire material, temperature range and phase.
• Wire Gauge Choice for Safe Voltage Drop: This determines the lightest gauge of wire that can be used over a run (circuit) that maintains adequate voltage.
• Circular Mils and Voltage Drop: This computes voltage drop based on wire diameter in circular mils instead of wire gauge.
• Electricity Usage Cost: This computes the cost of electricity for the use of a piece of equipment based on the power consumption rate, duration and cost of electricity.
• Electricity Consumption: This computes the amount of electricity consumed by an electrical appliance or motor over time.
• Rolling Offset: This computes the travel (T) and run (R) of a rolling offset used in conduit piping based on the offsets and angles.
• Diameter of AWG Wire: This provides the diameter of wire based on the American Wire Guide (AWG) gauge in mils and millimeters, and it also provide the cross-section area in square millimeters.
• P = V² / R: This computes power (Watts) based on the voltage (V) and resistance (R).
• DC to AC Converter: Computes the approximate voltage of Alternating Current (AC) from the voltage of Direct Current (DC).
• Diameter to Circular Mils: Computed the circular mils of a wire and the cross-section area based on the wire's diameter.
