Material of connector body; C. K Strip length may be specified as a single — nominal — value if tested as specified in paragraph 7. For testing a splicing connector or run and tap connector in which each ul 486a standard is secured by a separate means, the sample set is to consist of two connectors for each combination of connector and test conductor to be tested. The information sheet — ul 486a-486b for each unit container — shall be packed in the packaging container. Otherwise the test is to be conducted without the insulation assembled to the connector.
Samples tested in Test A, Insulation Puncture, may be used for Test B, Flashover. Exception: If agreeable to those concerned, samples may be subjected to more than one test. The observance of the requirements of this Standard by a manufacturer is one of the conditions of the continued coverage of the manufacturer's product. Addition to the Scope to Address Use of Ferrules and Adapters 2. A product whose features, characteristics, components, materials, or systems conflict with specific 468a-486b or provisions of this standard cannot be judged to comply with ul 486a-486b standard. Lift the setting wheel off the axle.
Other coatings may be used if found by investigation to be acceptable for the purpose. The test potential is to be 2200 volts for a connector rated 300 volts and is to be 3400 volts for a connector rated 600 volts — 1000 volts for signs and lighting fixtures luminaires. The strip length applies to all insulated connectors with which the tool is used. They are subject to revision as further experience and investigation may show is necessary or desirable. Other class and strand configurations may also be covered as indicated by marking. For Preliminary Review Only: Clarify that Aluminum Test Conductors can be Compact, Compressed, or Concentric Stranding 5. For Preliminary Review Only: Test B Flashover Clarification 6.
Die index number, or 4. The samples are to be prepared as described in paragraph 15. For connectors for use with a crimping tool, crimping die design and number of crimps; and G. Insulated connectors not covered in Item A, B I. Cracks are acceptable if the assemblies comply with the requirement in Dielectric Voltage- Withstand After Drop Test, Section 16. When using Table ul 486a standard Composition with a specific gravity 1.
These requirements also cover ampere-rated connectors intended for use in appliances and equipment and that comply with the requirements specific to those appliances and equipment. This series of tests is referred to as the mechanical sequence. For one series, samples of the connector axe to be secured to the combination of conductors of the smallest cross-sectional area, or the the smallest conductor, if only one conductor is intended to be secured; and for the second series, the samples are to be secured to the combination of largest total cross-sectional area, or the largest conductor, if only one conductor is intended to be secured. Each assembly is to be dropped four times so that an impact occurs at the top, bottom, sides, and edges, except that the samples subjected to minus 10°C 14°F are to be dropped only once so that the point of impact is that judged to be the most severe from observation of the drop test on the as received and oven-conditioned samples. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Once the crimped contact passes the pull test , measurements for the crimp indent , requirements.
August 24, 2 — 3 August 24, 4 October standarrd, 5, 6 August 24, 6A October 8, 7,8 August 24, 9 October 7, 10, 11 August 24, 12, 12A, 13 October 8, 14, 15 October 7, 16, 16A August 24, The connector is acceptable if it does not become separated from the conductor or conductors after completion of the test. Breakage or tearing of the insulation of an insulated connector is acceptable in the pullout test. The first stated value is the requirement. The connector is acceptable if it does not become separated from the conductor or conductors after completion of the test. Exception: A smaller than No.
The information sheet — one for each unit container — shall be packed in the packaging container. No: Revision , Held Pull Tester Safety Warnings and Information Read and understand all of the instructions and , wear eye protection could result in serious eye injury from flying debris during test. These requirements cover terminal-type wire connectors designed for use with No. After removal from the water it is to be dried with a soft cloth to remove all surface water before being reweighed. The dielectric voltage- withstand test on an insulated connector is to be conducted with the conductors stripped to the marked nominal strip length. Exception: Uninsulated pressure wire connectors both terminal and splicing type that are compression tool applied may be used in circuits rated 35,000 volts or less. This symbol may consist of an individual catalog number, a type designation, a size designation, such as 12, or an equivalently significant symbol.
Connectors employing extended covers or sleeves may have the wires pre-inserted, but not crimped, prior to the oven aging. For horizontally mounted connectors ul 486a-486b an assembly ul 486a-486b one or more sample sets of connectors, bus bar sections are to be located 2 feet in front, 2 feet in back and 2 feet on each side of the test assembly. A connector that has openings that would allow the entrance of shot, thereby possibly resulting in flashover, is to have those openings closed with tape, petrolatum, epoxy, silicone, rubber, or other acceptable material; and the exposed tang of a terminal connector is to be similarly treated. Tearing or breaking of the insulation is acceptable if the results of a repeated dielectric voltage-withstand test are acceptable. · When the hand tool is no longer capable , crimp tool for terminating specific contacts. To reduce the likelihood of flashover to the exposed tang of a ul 486a standard connector or the likelihood of insulation puncture, the outer surface of the connector insulation and the exposed tang may be supplemented with tape, petrolatum, epoxy, silicone, rubber, or other acceptable insulating material so that it does not interfere with the position of the outer electrode immediately adjacent to the conductor opening.
Sample Test Assembly 15 10. Material of conductor clamping screw; D. Exception: The marking may be on the unit container or on an information sheet packed in the unit container. Drop Test 23 Each sample is to be connected to a conductor or conductors in the intended manner, and the test potential is to be applied for 1 minute between the conductor or conductors and an outer electrode. This Standard contains basic requirements for products covered by Underwriters Laboratories Inc. Flashover between the conductor and the outer electrode is not acceptable. When connectors are used in such circuits, the stress-relief insulation prescribed by the manufacturers of shielded cables is to be provided when these connectors are installed.
