UL1278 UL507 Probe for Film-coated Wire 19.1 mm to Verify Accessibility of Live Parts
Description in UL1278 Clause 8.1~8.5:
8 Accessibility of Live Parts
8.1 An electrical part of a heater shall be so located or enclosed that protection against unintentional contact with uninsulated live parts will be provided, except that this requirement does not apply to a visibly glowing open-wire element and the connections immediately adjacent to the element. See 3.1 , 8.2, 32.7 and 32.1 4. Insulated motor brush caps do not require additional enclosures.
8.2 The requirement in 8.1 does not apply to the sheath of an isolated metal-clad element in a heater having provision for grounding the enclosure, although such a sheath is considered to be a bare live part when spacings are being measured.
8.3 In determining if an opening in an enclosure is acceptable, consideration is to be given to:
a) The proximity of uninsulated live parts (as determined by applying 8.1 , 8.2, 8.4, 8.5, and 8.1 5 and
b) The possibility of the emission of burning insulation, molten metal, and similar materials through the opening (as determined by applying 7.3 – 7.6.) Test Finger Probe
8.4 To reduce the likelihood of unintentional contact that may involve a risk of electric shock from an uninsulated live part or film-coated wire, an opening in an enclosure shall comply with either (a) or (b).
a) For an opening that has a minor dimension (see 8.8) less than 1 inch (25.4 mm), such a part or wire shall not be contacted by the probe illustrated in Figure 8.3.
b) For an opening that has a minor dimension of 1 inch or more, such a part or wire shall be spaced from the opening as specified in Table 8.1 . Test Finger Probe
Exception: An integral enclosure of a motor need not comply with these requirements if it complies with the requirements in 8.5.
8.5 With respect to a part or wire as mentioned in 8.4, in an integral enclosure of a motor as mentioned in the exception to 8.4:
a) An opening that has a minor dimension (see 8.8) less than 3/4 inch (1 9.1 mm) is acceptable if:
1 ) Film-coated wire cannot be contacted by the probe illustrated in Figure 8.2;
2) In a directly accessible motor (see 8.9), an uninsulated live part cannot be contacted by the probe illustrated in Figure 8.4; or
3) In an indirectly accessible motor (see 8.9), an uninsulated live part cannot be contacted by the probe illustrated in Figure 8.1 .
b) An opening that has a minor dimension of 3/4 inch (1 5.1 mm) or more is acceptable if a part or wire is spaced from the opening as specified in Table 8.1 . Test Finger Probe
Standard:UL398 Fig 8.2(PA170B),UL507(PA170D),UL749 Fig 2,UL982 Fig 58.6 and UL1278 Fig 8.2(PA140A).
