)x{0fjt%BZ$?uM\!6GOU7Z^BTwP; A few Utility company transformers are large, generally green in color, and can range from a small box (3w x 3d x 2h) in a residential neighborhood, to a large enclosure with oil-filled cooling fins (7w x 7d x 6h) on a large pre-concrete base. In general, a service drop must be at least 12 feet above the ground (grade) as well as sidewalks and residential driveways. 6T^\eun\#H"Ein$F4+O`Tbj;Vu=!v.D=3C;iA^(jx.\lbE?0-{)K.8Y\i.\9K.

While the underground services eliminate unattractive overhead pole lines, cabling and transformers, the installation of utility company transformers presents challenges of a different sort. Energy Efficient Transformer require a minimum of 3`` clearance from ventilated openings. Section 4.10 Required Vegetation Clearances (PDF, 5.3 MB) Tree Planting Matrix Tables (PDF, 5.3 MB) . /AcroForm 169 0 R
The clearance requirement is clearly marked on the nameplate of the Transformers. Transformers produce heat in operation, so must have clearance to obstructions Resolution: Older, non-EE Ventilated dry type Transformers must be installed so that a minimum of 6 inches clearance is available between a ventilation opening and any wall or other obstructions. %%EOF

In general, any electrical panel that has 0 to 150 volts going through it needs to have at least 36'' of clearance around it. Here's a little insight.
GENERATOR CLEARANCES The general rule-of-thumb is to leave 5 feet between generators and between a generator and other equipment, walls, or obstructions. To receive a TS/SCI clearance, follow these steps: 1. The successful operation of a transformer is pendent on proper installation as well as on proper design and manufacture. Note: Due to the large size of this document (approximately 20 MB), downloading or printing may take several minutes, depending on the speed of your modem and printer capabilities. Generally, a transformer located near a building requires 4ft clearance from the building vertical surfaces, assuming no windows from grade to 18ft.
