Temporary Installations

Section 590.3

Section 590.3 specifies the length of time that can be considered temporary as either during a period of construction (which could in some cases extend for more than a year, possibly even a few years) and/or 90 days.

Temporary holiday decorative lighting would fall under the 90-day limit.

Temporary wiring for emergency installations (such as a power outage) is covered by Section 590.3(C), and Section 590.3(D) requires temporary wiring to be removed once the need for it has ended, such as when the permanent wiring is finished or functioning again.

As noted earlier in this section, Article 590 is more flexible with regard to the wiring methods that may be used. For example, for feeders and branch circuits, Sections 590.4(B) and (C) specifically permit the use of hard usage or extra hard usage flexible cord selected from Table 400.4, or Type NM cable in buildings where NM cable could not be used for permanent wiring. This overrides some of the ordinary restrictions on the use of flexible cord in Section 400.8 and Type NM cable in Section 334.12.
