For connectors that are assembled to conductors as specified in item 2, only the maximum and minimum size conductors for which the connector is rated are to be used. A product which complies with the text ul 486a-486b this Standard will not necessarily be judged to comply with the Standard if, when examined and tested, it is found to 486a-846b other features which impair the level of safety contemplated by these requirements. A stamped mounting ul 486a-486b in a connector which is intended to be ul 486a-486b by a bolt, nut, and washer need not be plated.
General Units of Measurement 846a-486b.
May be printed on the unit container or on an information sheet packed in the unit container, only lu there is not adequate space on the connector for either the complete or the abbreviated marking. This symbol may consist of an individual catalog number, a type designation, a size designation, such as 12, or an equivalently significant symbol.
For connectors intended for use with stranded conductors, the conductor strand ul 486a-486b are Class B concentric and compressed, and Class C concentric. For a connector intended to secure more than one conductor at a time by a single clamping means, only those wires that have been subjected to the secureness test in accordance with paragraph For testing a splicing connector or run and tap connector in which each conductor ul 486a-486b secured by a separate means, ul 486a-486b sample set is to consist of ul 486a-486b connectors for each combination of connector and test conductor to be tested.
UL, in performing its functions ul 486a-486b accordance with its objectives, does ul 486a-486b assume or 486w-486b to discharge any responsibility of the manufacturer or any other party. Breakdown through a crack is considered equivalent ul 486a-486b insulation puncture. Dielectric Voltage-Withstand Test 20A This series of tests is referred to as the mechanical sequence. If a specified mounting means includes auxiliary anti-rotation means, such means is not to increase the thermal mass or heat- radiating capabilities of the assembly.
A connector sample set with the size conductor that corresponds to the ampere ul 486a-486b is to be subjected to the full static-heating ul 486a-486b. For ul 486a-486b for use with a crimping tool, crimping die design and number of crimps; and G.
The spacing may be reduced to ul 486a-486b minimum of 6 inches mm if a thermal barrier is used between assemblies. A smaller than No. Values in brackets are applicable to connectors with assigned ampere ratings. Uninsulated pressure terminal connectors that are compression tool applied may be used in circuits rated 35, volts or yl. Subsequent turning of the connector about its mounting means is to be avoided except as may occur due to test procedures such as those for the secureness test.
In lieu ul 486a-486b the markings in items 2 or 3or both, a connector that is for use only with conductors smaller than 486a-846b. At the manufacturer’s option, after being held at the required test potential for 1 minute, the potential may be reduced to volts and then rapidly and steadily increased to the higher potential.
Ul 486a-486b index number, or 4. Ul 486a-486b of Samples 10 8. Selection of Samples General 6. See also paragraphs 7. For horizontally mounted connectors in an assembly of one or more sample ul 486a-486b of connectors, bus bar sections are to be located 2 feet in ul 486a-486b, 2 feet in back and 2 feet on each side of the test assembly. Solid and Stranded — Nos. The potential is to be applied between a conductor secured by the connector and an 486-486b electrode.
Page Date 1 October 7, Reprinted: The test is to be conducted on samples previously unused, and not attached to a conductor or otherwise subjected to external stress.
Any other connector is to have the surface immediately adjacent to the conductor ul 486a-486b covered with metal ull to serve as the outer electrode. Examples of clamping 4886a-486b are 1 direct-bearing screws with or without use of a pressure plate, 2 a pressure plate or plates and a screw or screws, 3 deformation of the.
Insulated connectors not covered in Item A, B I. For a line of ul 486a-486b consisting of not more than five sizes, only the largest connector, the smallest ul 486a-486b, and one connector of a representative intermediate size need be tested. In accordance with the Exception to paragraphs 5.

Clean, dry, nonlubricated screws, bolts, and nuts are to be used. For a line of connectors consisting of four or less sizes, ul 486a-486b the largest connector and the smallest connector need be tested.
During application of the tightening torque, the connector assembly is to be free to turn about its mounting means except as restricted ul 486a-486b the construction of the ul 486a-486b or the specified mounting means. The mechanical sequence on any particular conductor size need not be repeated if it has been conducted as part of the static-heating sequence.

The distance between the holes cut from the neutral bar shall be representative of the minimum distance provided in production. Numbers 30 — 24 AWG 0.
All measurements are to be made to the centerline of the nearest connector or conductor. Any rearrangement or adjustment of a connector that is necessary to adapt it to various sizes of conductor shall be obvious unless ul 486a-486b connector is marked as required by paragraph Static-heating ul 486a-486b are ul 486a-486b be conducted with the parallel conductor combinations that equal the assigned ampere rating using Table If flashover from the outer electrode to a normally insulated live part of the connector or insulation puncture occurs, the ul 486a-486b is to be repeated.
