According to NBFAA minimum standards, how shall electrical splices be made?

• A. Twisted, hot soldered and covered with listed electrical tape or secured with solderless crimp connectors.
• B. Splices may be twisted and taped only.
• C. Splices require compression connectors only.
• D. Solders are required without tape.

Answer: (A)

Splices must result in a secure electrical connection that is properly insulated. NBFAA minimum standards require twisting the conductors together and forming a solid connection, then either soldering to ensure a low-resistance, durable joint and covering it with listed electrical tape, or using a listed solderless crimp connector to complete the splice. This combination provides both mechanical strength and reliable insulation, protecting the joint from moisture and damage.

Twisting and taping alone can be unreliable over time and under stress, so it doesn’t meet the standard. Requiring only compression connectors or soldering without insulation also fails to meet the insulation and protection requirements that the standard mandates.
