Introduction to Cast Junction Boxes

Transcription

1 UA2 Introduction to UA2 I Purpose of Enclosure Enclosures are used to protect personnel against accidental contact with enclosed electrical devices or connections and to protect the enclosed devices or connections against specified external conditions. They also serve as intermediate pulling and splicing points in a conduit system. II Design of Enclosures Enclosures are offered in different designs and construction to permit their use in various locations and areas. These are as follows: Non-hazardous Locations: Weatherproof boxes are so constructed as to be suitable for use outdoors under normal conditions. If it is necessary to prevent the entry of water under extreme conditions of weather, boxes listed as watertight or raintight are recommended. 2 Raintight boxes are so constructed as to exclude a beating rain. All boxes in this catalog which are designated as raintight have been so listed by Underwriters Laboratories, Inc. Watertight boxes (NEMA Type 4) are constructed to meet the requirements listed under "NEMA DATA" on Page UA. 4 Submersible Boxes are so constructed that they will exclude water when submerged under specified conditions of pressure and time. Dust-Tight Boxes are so constructed to meet the requirements listed on Page UA under "NEMA DATA". Hazardous Locations: Consult Section V for our complete line of Hazardous Location Enclosures. III Advantages of Cast Enclosures Cast metal enclosures have the advantage over formed (fabricated) sheet metal enclosures for the following reasons: A They are of one piece construction and do not have the disadvantages of spot welded seams usually found in formed sheet metal boxes. B They have greater mechanical strength, have thicker walls and are suitable for drilling and tapping at the factory or in the field. C They are corrosion resistant and can withstand more mechanical abuse. IV Comparison of Enclosures in Various Cast Metals CAST IRON BOXES will provide long life, are inherently corrosion resistant and have the lowest initial cost. CAST ALUMINUM BOXES are lightweight, non-rusting, non-sparking, and non-magnetic. They are subject to corrosion under certain alkalis conditions such as encasement in concrete unless provided with a suitable coating. CAST BRONZE BOXES (optional) will provide long life under adverse atmospheric conditions, are non-rusting, non-sparking and non-magnetic. V Finishes on Cast Enclosures CAST IRON - The hot-dip galvanized finish which is applied to all our cast iron boxes will conform to ASTM Designation A-, Class A and NEMA requirements for rustresistance. Other protective finishes such as various types of paints or plastic coatings can be supplied. CAST ALUMINUM - supplemental finishes are not normally required on cast aluminum enclosures. Special finishes such as epoxy coating, anodizing or plastic coating to meet specific environmental conditions can be applied. CAST BRONZE is inherently corrosion resistant. Supplemental finishes are usually not required on cast bronze. VI Hardware Used on Cast Enclosures CAST IRON BOXES are furnished with Stainless Steel screws. Silicon bronze screws are available on most enclosures. CAST ALUMINUM BOXES are furnished with stainless steel screws. CAST BRONZE BOXES are furnished with either brass or silicon bronze screws. VII Specification of Extras on Cast Enclosures The type of holes to be provided for the entrance of conduit into the enclosure are defined under "Instructions for Ordering Boxes" on Page UA4. VIII Specification of Extras on Cast Enclosures The "Standard Construction" of each type of enclosure is shown on each listing. The extras which are available and must be specified are shown under "Additional Cost Items" on Pages UA6, UA. IX Delivery Schedules Cast enclosures are normally produced to order. However, faster deliveries can be provided for some of the more commonly specified styles and sizes. Contact your Local Representative for delivery information and assistance to expedite shipments of the material required on your order.

2 UA UA Cast & Cast Aluminum Boxes NEMA Data Our cast junction boxes are designed, constructed and tested to comply with NEMA standards. The following chart has been prepared to provide a quick reference for selecting enclosures to meet specific NEMA requirements. A brief description of the more common types of enclosures used by the electrical industry relating to their environmental capabilities follows. Please refer to the appropriate sections of NEMA Standards Publication No Enclosures for Electrical Equipment (000 Volts Maximum) for complete information regarding applications, features and design tests. Definitions Pertaining to Non-hazardous Locations Type enclosures are intended for use primarily to provide a degree of protection against contact with the enclosed equipment. Type 2 enclosures are intended for indoor use primarily to provide a degree of protection against limited amounts of falling water. Type Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow and windblown dust; and that will be undamaged by the external formation of ice on the enclosure. Type R enclosures are intended for outdoor use primarily to provide a degree of protection against falling rain, sleet, and external ice formation. Type S enclosures are intended for outdoor use primarily to provide a degree of protection against windblown dust, rain, sleet, and provide for operation of external mechanisms when ice laden. Type 4 enclosures are intended for indoor or outdoor use primarily to provide a degree of protection against windblown dust and rain, splashing water, and hose-directed water. *Type 4X enclosures are intended for indoor or outdoor use primarily to provide a degree of protection against corrosion, windblown dust and rain, splashing water, and hose-directed water. Type enclosures are intended for indoor use primarily to provide a degree of protection against dust and falling dirt. Type 6 enclosures are intended for indoor or outdoor use primarily to provide a degree of protection against the entry of water during occasional temporary submersion at a limited depth. (0 6 ft.) Type 6P enclosures are intended for indoor or outdoor use primarily to provide a degree of protection against the entry of water during prolonged submersion at a limited depth. (24 6ft.) Type 2 enclosures are intended for indoor use primarily to provide a degree of protection against dust, falling dirt, and dripping non-corrosive liquids. Type Type 2 Type of Type Type R Type2K Enclosure Type Type 2 Type S Type 4 Type 4X Type 6 Type YS & YS-A * YL & YL-A * YF YF-A * YW & YW-A * YU YR YT YC Type 2K enclosures with knockouts are intended for indoor use primarily to provide a degree of protection against dust, falling dirt, and dripping non-corrosive liquids other than at knockouts. Type enclosures are intended for indoor use primarily to provide a degree of protection against dust, spraying of water, oil, and non-corrosive coolant. Definitions Pertaining to Hazardous (Classified) Locations Type enclosures are for use indoors in locations classified as Class I, Groups A, B, C, or D, as defined in the National Electrical Code. See Section V. Type enclosures are for use in indoor locations classified in Class II, Groups E, F, or G, as defined in the National Electrical Code. See Section V. YW-T & YW-T-A * YCW & YCW-A * YPW & YPW-A * YBW & YBW-A * * Aluminum enclosures with stainless steel hardware may be ordered with optional spray applied epoxy powder coating to meet Type 4X corrosion protection.
