Building Department - Electricity Types
Basic Service Types
Overhead - If your property is adjacent to ComEd overhead facilities, in most cases your service will be an over head service wire, installed between the pole and your service wire attachment. Overhead to Underground - If you desire direct buried cable because of obstructions or aesthetics, ComEd will provide such installation if practical. ComEd may elect to install a service pedestal near the base of the pole.
Underground - If your property is adjacent to a ComEd underground facility, in most cases you will be served by an underground service cable.
(Note: Charges may apply to any of the above installations.)
Installing or Revising Electric Service
There are five simple steps you must take to have electric service installed for the first time or revised at your residence.
- Contact an electrician or electrical contractor.
- Contact ComEd.
- Contact your local governing body.
- Complete all work required of you and your electrician.
- Notify ComEd and your local governing body that the work is completed.
Before you begin, you should have a clear idea of what you want to accomplish. You also should look ahead and decide if you're likely to make future improvements that could affect the work you're about to do. If, for example, a room addition, deck, patio, or pool is in your future, where is it likely to be and how will it co-exist with your current project? Even if your future intentions are only vague notions at this stage, you should talk about them with your electrician and ComEd; they can suggest alternatives that can avoid future problems with service restorations or even having to undo all the work you are about to undertake.
Contact Your Electrician
Since the safety of you and your loved ones is a top priority, ComEd strongly recommends (and most municipalities require) that you select a licensed (certified by a governing body) and bonded (an employee placed under guarantee by a financial institution for unforeseen financial loss) electrician to perform any electrical work. To ensure quality and your safety, the electrician's work will be reviewed and approved by your local governing body after the work is completed.
NEVER CONSIDER THE ELECTRICAL WORK TO BE COMPLETE BY YOUR ELECTRICIAN UNTIL THE LOCAL GOVERNING BODY HAS INSPECTED AND APPROVED THE WORK PERFORMED AND COMED HAS SUCCESSFULLY MADE FINAL CONNECTIONS AND INSTALLED A METER.
As you discuss your electrical needs with the electrician, the following service requirements need to be determined:
- Will the new electric service requirements be overhead or underground?
- Will the new service be rated at 100, 200, or 400 amps?
- What is the required voltage?
- What is the preferred location of the new meter fitting?
There are several factors to consider when planning your new service location and wire/cable route. The rule here is to think ahead. The service route should not conflict with future improvements to your property. Advance planning at this stage pays big dividends later. For example, pouring a cement patio over an underground service route may seem harmless now, but what happens when you have to break it up to have a failed cable repaired? Disasters like this are easy to avoid with advance planning - a few feet of conduit installed at the outset can make a big difference later.
The electrician's quote normally is based on his labor and material. It does not reflect any charges that may be applied by ComEd or other utilities. ComEd recommends that your electrician not start work on your residence until the requested metering equipment, type of service and location of the meter has been agreed upon by your ComEd representative, and necessary permits have been obtained from your local governing body.
Contact ComEd as soon as possible after you and your electrician have come to an agreement of what will be required. Advance notice will enable us to complete our work within your time schedule.
During normal business hours, call our toll free number, 1-800-Edison-1 (1-800-334-7661) and ask for the C.D.C. (Customer Design and Construction) team that services your area. Be prepared to provide:
- Service address, as assigned by the postal authorities, or a ComEd account number.
- The customer's name.
- The customer's home and daytime phone numbers.
- The mailing address to which all correspondence and billing will be sent.
- The electrician's name and phone number.
- Type of service (overhead or underground).
- A brief description of why the work is being done, and future plans as they apply to your residence (upgrading, building addition, installing swimming pool, patio, garage, deck, new residence, septic field location, etc.)
- The preferred meter location.
- The voltage and amperage requirements.
- Whether a meeting is required with a ComEd representative to clear up any questions.
The information that you furnish in this initial contact will be forwarded to a ComEd representative for review. Shortly thereafter, the ComEd representative will contact you or your electrician by phone or mail.
A formal sketch or detailed drawing may be needed to clarify your proposal. You may be advised to utilize an alternate plan or make certain changes to your property or residence to facilitate your request. Charges may apply based upon type of service requested.
Contact Your Local Governing Body for Permits, Inspections, and Approvals
You are responsible for the following items prior to ComEd providing service:
- Obtain all permits and approvals required by your local governmental authorities.
- Any costs or fees incurred in obtaining permits, inspections or approvals.
- Inspections and approvals of your electrical facilities for compliance with Electrical Codes.
If a governmental authority requires ComEd to disconnect electric service because of a violation of the Electrical Code, ComEd will restore service only after approval by the local authority and after payment by you of charges for disconnection and restoration of service.
Work Done By You and Your Electrician
While exercising the skills and knowledge required to construct a safe and reliable electric service at your residence, your electrician will be following all local and national Electric Codes, and must meet ComEd requirements.
Once the electrician has completed the work, your new or revised electric service may be temporarily connected to allow your residence to receive electricity through your new meter fitting.
For revised services, the electrician will make all temporary connections from the outside of your residence. This can be accomplished by installing temporary wires from your old service installation to the new service installation. This is necessary to allow the electrician to energize the newly installed equipment to assure that the system is functional and permit continuity of service.
EXERCISE CAUTION NEAR TEMPORARY WIRING.
Your meter may be unplugged during this time period and you will receive an estimated bill based on your normal energy use.
Notify ComEd and Your Local Governing Body
When the electrician's work has been completed and the site is ready, please contact your local governing body for an electrical inspection.
After the local governing body has approved the new/revised installation, ComEd will be notified directly. ComEd must receive this notification before your service request can be scheduled for field completion.
Site readiness may be determined by some or all of the following:
- Remove fences.
- Trim trees.
- Locate customer-owned underground facilities.
- Provide proper final grade and clearances.
ComEd may refuse to connect service if your metering equipment and installation fails to meet all requirements.
YOU ARE RESPONSIBLE FOR THE ADEQUACY, CONFORMANCE TO CODES, SAFETY AND RELIABILITY OF THE EQUIPMENT AND FACILITIES OWNED, INSTALLED AND MAINTAINED BY YOU AND YOUR ELECTRICIAN.
CO_MED RESERVES THE RIGHT TO EXAMINE AND TEST ANY EQUIPMENT CONNECTED TO ITS LINES, AND TO REQUIRE THE CUSTOMER TO FURNISH INFORMATION NECESSARY TO DETERMINE THE OPERATING CHARACTERISTICS OF THE EQUIPMENT.
