Wavelength Engineering

The enclosures are manufactured to suit IP 54/55 requirements.

The basic structure provides a rigid platform based on a C-channel design.  The structure is comprised of 12 and 14 gauge Aluzinc steel.  The components of the framework is secured by self-tapping screws which require little or no maintenance.

Each section is equipped with removable rear and side panels secured with threaded screws.

Full height barriers are provided to isolate each vertical section.

Removable end plates on each end of the MCC cover all horizontal bus and horizontal wireway openings.

Four roof-mounted lifting eyes are provided for each section.

Vertical sections are 90.5” high excluding lifting eyes, 19.7” (500 mm) wide and 19.7” (500 mm) deep.  The widths for incoming main sections are either of 19.7”, 23.6”, 27.6”, 31.5”, or 39.4” as required.

Structures allow a maximum quantity of [6] 12” Units or [12] 6” Units per vertical section.

Removable 14 gauge top [and bottom] plates are provided for top conduit entry/exit.

No rear access is required to remove any internal control components. Panels are dust and vermin proof.

 

Finish:  

Steel parts shall be prepared for painting by a four-stage wash system consisting of:

Degreasing process

Fresh water rinse

Zinc phosphate immersion

Fresh water rinse

Following the wash system all steel parts are dried in an oven.  After cleaning and drying, the steel parts are coated with a minimum 3.0 mils dry film thickness of light gray Interpon polyester powder, followed by a 15 minute curing process. The paint shall have a salt spray rating according to ASTM B117-07a of 2000 hours. Paint finish color shall be textured ANSI # 61 light gray. 

Each enclosure contains an engraved stainless steel nameplate with white background and black lettering located on the top of the vertical wireway door. 

Handling

The line up are divided into shipping splits.  The maximum shipping length generally does not exceed 60” (1524 mm). Any lineup that is in excess of 60” (1524 mm) are divided into shipping splits accordingly.

Each Panel is provided with adequate lifting eyes.

A removable shipping base is provided with every shipping split.

 

WIREWAYS

Each 19.7” structure contains a 4” wide vertical wireway with an option for an 8” wide wireway.  The vertical wireway depth is 11.5” providing 40.25 square inches of cross sectional area for control and load wiring. The wireway is isolated from the main bus compartment by use of suitable barriers. 

Each vertical wireway is equipped with a window over the bus splices to allow for visual inspection and ease of routine maintenance.

Each wireway is equipped with a 14-gauge full height hinged door securely fastened with three steel quarter-turn latches.  The vertical wireway doors swing open 105 degrees opposite of the unit doors for maximum accessibility.

Each vertical wireway contains field-wiring terminals for power and control.  Terminal block assembly are finger safe rated to meet IP20.

The top horizontal wireway is generally 10” high.  The top horizontal wireway is covered by a 14 gauge steel hinged door secured by a steel quarter turn latch.

The bottom horizontal wireway is 7” high.   The bottom wireway contains the ground bus and be covered by a 14-gauge steel hinged door secured by a steel quarter turn latch.
