In addition to safety, fire-resistant electrical tape can increase the longevity of electrical connections. Regular electrical tape may degrade over time, especially under extreme conditions, leading to insulation failures. The durability of fire-resistant tape means it can withstand harsher conditions, thereby extending the lifespan of electrical installations.

Follow up this first step by wrapping four half-lapped layers of rubber insulating tape over the cambric tape, which creates a moisture barrier and provides the primary insulation in the connection. Finally, over-wrap the assembly with a minimum of two half-lapped layers of vinyl electrical tape. This should extend approximately two tape widths beyond the ends of the rubber tape. Stretch this tape as you wrap it so you get good conformance to the underlying structure. This also helps complete the moisture seal.
