Hello.....my name is XXXXX XXXXX I will be happy to assist you with your electrical question. My goal is to exceed your expectations on Just Answer!
1) Hello Dave..........depending upon your location in the United States, electrical hourly labor rates are approximately $60 per hour for an independent electrical contractor up to $125 for a union electrical contractor. The average hourly rate for most independent contractors is around the $60 to $75 per hour range.
2) As you know, most electricians price their quotes on a "per opening" basis. A "per opening" is the quantity of all devices in a box. For example, a 3 gang switch box would be considered as 3 openings and not just 1 opening. A 2 gang or quad duplex receptacle wall box would be considered as 2 openings and not 1, etc.
3) With the "per opening" price in mind, most common pricing averages around the $60 to $75 price range for an independent electrical contractor and that is for "open wall" construction. In your application, you will also need to factor in the additional cost of purchasing and installing metal "Wiremold".
In your application, you will most likely end up fishing some enclosed walls using either Flexible Metal Conduit or Metal Clad cable or Romex cable. Therefore I would increase the "per opening" price as necessary depending upon existing conditions.
I also add a few dollars more to each device if they will be "Decora" type and not the standard types of devices to cover the additional cost of the Decora's.
Same thing with GFCI receptacles, add the additional cost for each device to cover the additional material cost of the GFCI.
CAT 5E computer, RG6 Coaxial and CAT 3 telephone cabling averages around $90 per run. Possibly lower if the run is shorter. The use of "Keystone" inserts @ the wall plates is the most common for the low voltage terminations.
Home run pricing for a regular 15 or 20 amp single pole circuit averages around $125 per circuit. If using AFCI for the home runs, average price is around $175 per circuit. If using GFCI for the home run, average price is around $165 per circuit.
Ceiling fans average around $75 to install providing electric is at the ceiling. If installing a wall switch for a ceiling fan, I add on an additional $140 to cover the cost of the combo fan switch and labor to install the wall switch.
For 240 volt appliance circuits, I double the price of the home run and the device opening.
Don't forget to include any permit fees, municipality licensing fees, additional bonding fees and/or inspection fees.
I total up the quantity of openings, home runs, etc and then I add an additional 10% to 15% on the project to cover for any miscellaneous items that I may have omitted.
4) To meet the existing 2011 National Electrical Code, the following need to be included:
A) Arc Fault Circuit Breakers for all living areas, ie, bedrooms, living room, family room, etc.
B) Bathroom needs to be on a 20 amp dedicated circuit and GFCI protected at the receptacles or the use of a GFCI circuit breaker for the branch circuit. I do not recommend sharing the 20 amp dedicated circuit for the receptacles in other bathrooms. Always best to wire each bathroom with its own dedicated 20 amp circuit.
C) Duplex receptacles need to be the Tamper Proof type
D) Inter-communicated smoke alarms in each bedroom and in the hallway. A carbon monoxide alarm in the hallway area outside of the bedrooms. To save on labor, you can also use wireless inter-communicated smoke alarms. Some manufacturers also make a combo smoke/carbon monoxide unit.
E) Kitchen countertop receptacles require a minimum of (2) two dedicated 20 amp circuits which must be GFCI protected. Nothing else on these circuits, no lighting and not shared with any other appliances or rooms.
F) Recommend that the microwave oven area have its own dedicated 20 amp circuit and not shared.
G) Dish washer and garbage disposals may be on a shared neutral circuit, but each should have their own dedicated 15 or 20 amp circuits depending upon the nameplate rating of the appliance.
H) Wall switches either need to have a neutral conductor installed or future accessible means to be able to install a neutral conductor. This requirement is for Occupancy Sensors that require a neutral conductor.
