Switch Boards

Parks line of Service Entrance Switchboards and Distribution Switchboards are single or multiple cabinet systems that can be shipped as single units for NEMA 3R, NEMA 3R/12 or NEMA 4XSS applications. As NEMA 1 indoor enclosures, they can be shipped broken down to single cabinets. These switchboards are designed to meet the needs of main over current protection with properly coordinated distribution over current devices. Main or distribution disconnects can be circuit breakers, fusible bolted pressure switches or fusible knife switches.

Our switchboard design and construction is state-of-the-art and complies with all applicable Federal, UL and NEC specifications, as well as all U.S. utility requirements. Enclosures are constructed of heavy duty steel, and metering current transformer compartments can be customized to meet your utility requirements with hinged door and secure latch for utility company sealing. Metering current transformer compartments can be ahead of (Hot Metering), or after the main disconnect (Cold Metering). Potential transformer provision for complex metering is available. Park can also provide additive or subtractive metering designs. Top or bottom feed lug landings or bus heads to terminate in NEMA type spades are standard designs. Bus risers can be made with bends to pass around obstacles, go straight up, take a 90 degree bend to go through a wall, etc. The bus can go out the back of the switchboard through a wall, and then covered by a bus head enclosure to terminate with underground feeds, outside the building. Park can also hard bus from the transformer spades into the switchboard or switchgear. The standard bus withstand rating is 65kA.
