Yes, it is legal to use solder and Scotch 33 tape to secure branch connections in patient care areas.

The National Electrical Code (NEC) requires that all branch circuit connections be made up using "approved terminations." Solder and Scotch 33 tape meet this requirement.While knob-and-tube wiring is no longer a common method for wiring buildings, solder and Scotch 33 tape are still considered acceptable methods for making branch circuit connections in patient care areas.However, it is important to note that the NEC does not require the use of solder and Scotch 33 tape. There are other approved methods for making branch circuit connections, such as using wire nuts or crimp connectors.Ultimately, the decision of which method to use is up to the electrician. However, if the electrician chooses to use solder and Scotch 33 tape, they must do so in accordance with the NEC. Flag for review
