45.5 The test equipment shall include a transformer having an essentially sinusoidal output, a means of indicating the test potential, an audible or visual indicator of electrical breakdown, and either a manually reset device to restore the equipment after electrical breakdown or an automatic reject feature of any unacceptable product.
45.6 It the output of the test equipment transformer is less than 500 volt-amperes, the equipment shall include a voltmeter in the output drcuit to directly indicate the test potential.
45.7 If the output of the test-equipment transformer is less than 500 volt-amperes or larger. the test potential may be indicated:
a) By a voltmeter in the phmary circuit or in a tertiary-winding circuit;
b) By a selector switch marked to indicate the test potential; or
C) For equipment having a single test-potential output, by a marking in a readily visible location to indicate the test potential. When marking is used without an indicating voltmeter, the equipment shall include a positive means, such as an indicator lamp, to indicate that the manually reset switch has been reset following a diefectnc breakdown.
45.8 Test equipment other than that described in 45.4 — 45.6 may be used ii found acceplable to accomplish the intended factory control.
45.9 During the tests involving pnmary circuits, the primary switch is to be in the “On” position, both sides of the pnrnary circuit of the product are to be connected together and to one terminal of the test equipment, and the second test-equipment terminal is to be connected to:
a) Accessible dead metal: or
b) The secondary circuit.
lithe product employs a contactor in the control circuit, both the line and the load sides of the contactor are to be subjected to the test potential.
Exception No. 1: A product having circuitry not subject to excessive secondary-voltage build-up – such as resistive circuitry, or high-impedance winciings. and the like — In case of electrical breakdown during the test may be tested.
a) With a single-pole primary switch, if used, in the “oft’ position: or
b) With only one side of the primary circuit connected to the test equipment when the primary switch is in the “oW’ position, or when a primary switch is not used.
Exception No. 2: The primary switch is not required to be in the “oil position if the testing means applies full test potential between primary wiring and dead metal parts with the switch not in the “on” position.
46 Grounding Continuity Test
46,1 Each product that has a power-supply cord having a grounding conductor shall be tested, as a routine production.line test, to determine that electrical continuity exists between the grounding blade of the attachment plug and accessible dead metal parts of the product that are likely to become energized.
46.2 Only a single test need be conducted if the accessible metal selected is conductively connected by design to all other accessible metal.
46.3 Any acceptable indicating device — an ohmmeter, battery-and-buzzer combination, or the like — may be used to determine whether a product complies with the requirement In 46.1.
RATiNGS
47 Details
47.1 A product shall be rated in amperes or watts and volts, and may be rated for alternating current only. The rating shall include the number of phases, if the product is designed for use on a polyphase circuit, and the frequency. The voltage rating shall be in accordance with any appropriate single voltage or range of voltages. such as 100— 120, 208, 220 — 240, 254 — 277, 416. 440—480, 550. 575, and 600.
47.2 The product shall be rated in the number of cells in series which it is intended to charge.
MARKINGS
48 General
48.1 A product shall comply with the marking requirements specified in Sections 48 and 49. Unless otherwise stated, markings shall be provided on an outside surtace of the product.
48.2 A product shall be legibly and permanently marked with:
a) The manufacturers name, trade name, or trademark;
b) The date or other dating period of manufacture not exceeding any three consecutive months;
C) A distinctive (catalog) (model) number or the equivalent; and
ci) The input and output nominal voltage rating, frequency, and amperes or watts.
Exception No. 1: The manufacturers identification may be in a traceable code if the product is identified by the brand or trademar* owned by a private labeler.
Exception No. 2: The date of manufacture may be abbreviated or in a nationally accepted conventional code, or in a coded affirmed by the manufacturer provided:
a) The dale code does not repeat in less than 20 years.
b) The dale code does not require reference to the manufacturer’s records to determine when the product was manufactured.
