In rare occurrences, an alternate method of construction may be needed that is not mentioned in the applicable code. Even though these alternate methods may not be in the Electrical Code, they may be able to meet the intent of what the NEC^® is trying to accomplish.

The State Building Codes Division makes rulings on the acceptability of using alternate materials or methods of construction. These rulings are called Electrical Statewide Alternate Methods (SAMs) and are located here at the States website: Oregon Alternate Methods

To date, there are four alternate methods posted on the site for the electrical trade:

08-02 Underground Splicing of Equipment Grounding Conductors for Traffic Signal Installations.

08-03 NMB cable in outdoor conduit sleeves. (Rescinded)

09-01 Electric Vehicle Charging Equipment Services and Feeders.

22-01 Electrical Vehicle Supply Circuit GFCI Protection for Personnel

The rules below pertaining to alternate methods can be found here: Chapter 918 Division 8, 918-008-0095
