(a)This subpart I incorporates by reference NFPA 70 (incorporated by reference, see § 3280.4) including Part II of Article 550 of NFPA 70, and covers the electrical conductors and equipment installed within or on manufactured homes and the conductors that connect manufactured homes to a supply of electricity. However, Articles 550.4(A) and 550.4(B) of NFPA 70 shall not apply.
(b)In addition to the requirements of this part and Part II of Article 550 of NFPA 70, the applicable portions of other Articles of NFPA 70 referenced in this part must be followed for electrical installations in manufactured homes. The use of arc-fault breakers under the NFPA 70, are only required for general lighting circuits. Smoke alarms installed on a dedicated circuit do not require arc fault protection. Wherever arc-fault breakers are provided, such use must be in accordance with NFPA 70. Wherever the requirements of these standards differ from NFPA 70, these standards apply.
(c)The provisions of this standard apply to manufactured homes intended for connection to a wiring system nominally rated 120/240 volts, 3-wire AC, with grounded neutral.
(d)All electrical materials, devices, appliances, fittings and other equipment shall be listed or labeled by a nationally recognized testing agency and shall be connected in an approved manner when in service.
(e)Aluminum conductors, aluminum alloy conductors, and aluminum core conductors such as copper clad aluminum; are not acceptable for use in branch circuit wiring in manufactured homes. \[40 FR 58752, Dec. 18, 1975.
