Suppose an Electrical Worker needed to provide a cost estimate for a house with 223

outlets (sometimes referred to as box openings). The estimate does not include lighting fixtures, but does include all wired devices and outlets. Dimmers and time switches are extra. One 100 amp 240-volt service is included. One central furnace or one central heat pump without auxiliary heat is included. One telephone outlet, one TV outlet, and one electric water heater outlet are included. Devices are standard ivory with plastic plates. All wiring and material is full accordance with the NEC and local codes and is guaranteed

for one year. Electrical permit and inspection fee is included.

Using a cost estimating value of $30.00 for each electrical box opening, how much would the electrical installation estimate on this house cost (counting two gang boxes as two openings)?

a.$6,590.00

b.$6,660.00

c.$6,690.00

d.$6,960.00
