The **Outlets and Wiring for Room** calculator 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..

**INSTRUCTIONS:** Choose units and enter the following:

- (
**L**) Length of Room - (
**W**) Width of Room - (
**oS**) Outlet Spacing

**Wire and Outlets (WnO):** The calculator returns the number of outlet boxes to meet the separation and the approximate length of wire to rough-in the boxes. The length is in feet. However, this can be automatically converted compatible units via the pull-down menu. The calculator also returns an approximate amount of time to install the outlets after rough-in wiring is complete.

Electrical codes require outlets at regular intervals. This calculator computes the number of outlets needed in a room based on the dimensions and the amount of wire to connect them. This algorithm assumes that rough-in wiring for each outlet box requires an extra 8" for each run of wire (2 per box for in and out).

**Volume of a Room**: Computes the cubic feet (volume) of a room based on its height, length and width.**Areas of a Room**: Computes the square feet (area) of the ceiling, walls and floor of a room based on its height, length and width.**Room Paint Cost**: Estimates the gallons of paint needed and associated cost to paint a room based on the room dimensions, number of coats and the unit cost of paint per gallon.**Wallpaper for a Room**: Computes the number of rolls of wallpaper needed to cover the walls of a room based on the dimensions of the room and the rolls of wallpaper.**BTUs per Hour to Heat a Room**: Computes the energy (heat) required to heat a space of a certain volume by a specified temperature variance.**Insulation Rolls for Walls of a Room**: Computes the number of rolls or batts of insulation needed for the WALLS of a room based on the length and height of the four walls. The calculator assumes standard 16" spacing on the studs.**Drywall Materials for a Room**: Computes the number of drywall boards (4x8 or 4x12), number of drywall nails or screws and gallons of joint compound need for a room based on the room's dimensions.**Ceiling Tiles for a Room**: Computes the number of ceiling tiles needed to cover the ceiling of a room based on the dimensions of the room and the tiles.**Cost of Flooring a Room**: Computes the square feet of a room and then applies the price per square feet of different flooring products (e.g., hardwood, carpeting, tile)**Room Framing Cost**: Computes the number of studs and plate boards for a room and estimates the cost of framing based on the unit price of the lumber.**Outlets and Wiring for 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.

**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.**20A SP Switch Installation Time**: Estimate the installation time for 20 Amp Switches based on the level of difficulty and number of switches.

**EMT Conduit Weigh**t: 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.

**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.
