(Figure 5) Do not use lighters and matches as an open flame can burn the insulation. The use of shrink-wrap tubing is great for sealing and protecting electrical splices and connections but for real waterproofing, use CCs with heat sensitive adhesive on the inside.


be used is sometimes confusing. Vinyl Electrical Tape, which was once the norm, is better not used for anything other than very temporary situations, such as binding wires together just to pass them through a difficult area. Tape should not be used to bundle; use cable ties, split or spiral conduit instead. Vinyl Electrical Tape degrades with time and heat- it is never watertight and it leaves wires sticky when left in place for any extended period of time. In cases where you do want to cover a connection and it is not possible to use shrink tubing, the tape of choice is one that does not have any adhesive. The most common of these are silicone self-fusing (aka Rescue Tape) or rubber splicing tape. Both of these are capable of creating a waterproof connection. The silicone tape is a little easier to apply and comes in a variety of colors, but it is more expensive. Marine wiring is certainly no
