Myers Power Products manufacturers Power Distribution Centers to house its metal-clad switchgear, metal-enclosed switchgear and customer-provided equipment. Myers can ship a Power Distribution Center in one piece, with maximum dimensions of 64 feet long by 15 feet wide and approximately 130,000 pounds in weight. The advantages of a one-piece shipment are lower installation cost and less time spent in reassembling the building. To see photos of a completed Power Distribution Center being loaded onto a truck at our Corona, California facility, click here.
Our Power Distribution Centers are manufactured in accordance with the California Building Codes and the National Electric Codes, and can be built to meet any design requirements. Our standard design follows seismic zone 4 requirements.
Here are additional features of our Power Distribution Centers:
| Fabrication: |
We use an interlocking panel design that does not require a separate structure to support the walls or the roof. The exterior interlocking panels are normally made from 12-gauge hot-rolled pickled in oil steel sheets, but Myers also offers 11-gauge steel sheets and galvanneal, aluminum or stainless steel sheets. The interior panels are normally made from 16-gauge hot-rolled pickled in oil steel sheets. |

| Ratings: |
The roof live loading is 50 pounds per square foot. The floor live loading is 125 pounds per square foot. The wind loads are rated for wind speeds of 125 MPH. |

| Insulation: | Myers can provide the Power Distribution Centers with insulated walls, roof and floor if required. The walls and roof can be provided with fiberglass or a hardboard type of insulating material for an R-value up to 30. The base can be provided with insulation but this is a special blown in type of fiber material. |

| Base: |
Our Power Distribution Centers can rest on piers or on a flat concrete pad. Myers has even designed a Power Distribution Center which sat on 6 foot stilts (this design was special for the arctic area in the North Slope of Alaska). Myers' base for the Power Distribution Centers can be anywhere from 6'' high channel material to 24" I-Beam material. The base is welded together by expert welders, then cleaned and coated on with a coal tar epoxy. Once the epoxy has set, the base is flipped over and a durable non-skid gray floor enamel paint is applied. The floor is normally 3/16" steel plate but a 1/4" thick steel floor can be provided. |

|
| Doors: | The doors are provided with double wall construction and an insulated core. Minimum of two personnel doors are provided per enclosure. Doors are at least 14-gauge galvanized steel reinforced with welded frame construction. Panic hardware is provided to defeat all locks for emergency exit from the building. Doors are equipped with hydraulic door closer with hold-open feature. We also provide 14-gauge uninsulated hinged doors with three-point latching for equipment requiring rear access. All hinged doors are watertight. |

|
| Lighting: |
Our lighting consists of 4' long fluorescent twin-tube fixtures with a wrap-around prismatic diffuser. This provides fifty foot-candles of light, at a level of five feet above the floor level, at the switchgear and other equipment. The indoor lighting is controlled by three-way switches located at each main entrance. Each Power Distribution Center has a minimum of two 125 volt, 20 amp, 2 pole, 3 wire, grounded type, duplex receptacles, with one located at each personnel door. Interior emergency lights can be provided above each main door by means of a wall-mounted, self-contained, continuously charged battery powered unit with two lamps. Myers provides high-pressure sodium type exterior lighting above each entrance door. External lights are controlled by a common photoelectric cell. |

|
| HVAC: | Myers can provide the heating, ventilating and air conditioning system. Consideration shall be given to the ambient site conditions, the dimensions and heat retention of the building, and the heat dissipated by the electrical equipment (including future equipment) inside the building. Thermostatically controlled heating elements will maintain a minimum building temperature of 130 C (550 F). |
