Electrical Power Upgrade for
RESIDENTIAL STRUCTURES


The following guidelines shall be used for the installation of new electrical service to an existing structure.


1. If you are not familiar with working with high voltage wiring, we would recommend that you utilize a licensed electrician to
assist you with this change.

2. Apply for a permit from Pickens County Building Codes for a Power Upgrade. The cost for this permit is the minimum of
$50.00

3. Have new service ready for switchover from old service. Call for inspection when ready. Refer to your PERMIT NUMBER
when requesting an inspection. If your inspection passes, we will fax your power company to set or re-set the meter.

4. If you rewire all or part of a structure, you must call for a framing inspection so that we can inspect the electrical installation.
The contractor or owner must be present for this inspection.

5. Smoke Detectors: If you do any modifications to the interior electrical system, and you can get into the attic area to access
the wiring, it will be necessary to add a minimum of one (1) 110/120-volt electric smoke detector with battery back up in the
area of the bedrooms. If the home is rewired, it will be necessary to add 110/120-volt electric battery-back-up smoke
detectors inside all bedrooms and outside bedroom areas and on each level.

6. If meter cans and panel boxes are not located back-to-back, a main disconnect shall be installed on the exterior of the
structure, and a 4-wire system used to supply the sub-panel inside. Bond panel enclosure.

7. Bonding at the main panel goes to the neutral bus bar; bonding at a sub panel goes to the grounding bus bar. Remove the
jumpers in the sub panel so the neutral and grounding bus bars are isolated. Bond panel enclosure.

8. Bond all building metal, panel enclosures, and metallic pipes. Metal boxes must also be bonded.

9. Ground
rod
installation:
a. All electrical installations are required to have two (2) 8-foot ground rods installed 16 feet apart.
b. Top of grounding rods and ground wire shall be installed 8 inches below final grade. Do not cover until approved.
c. The ground wire must be a minimum of a # 4 soft copper continuous from meter can to both ground rods and
attached to the ground rods with UL approved direct burial type clamps.
d. The vertical ground wire going to the meter can from the ground rod must be protected using rigid non-metallic
electrical conduit up to 4 foot from grade level. Leave approximately 6 inches of ground wire unprotected at the top
of the conduit.

Electrical Power for an R.V.

1. You must have the three (3)-prong RV plug with an In-Use cover.
2. 110-volt outlets must be Ground Fault Circuit Interrupter (GFCI) protected and enclosed in an In-Use Cover.
