What makes Ancor electrical products unique?
Ancor was founded over forty years ago to provide wire and electrical products that are designed to withstand harsh corrosive environments. Ancor is the originator of Marine Grade® wire, which is built with features such as UV-resistant jacketing and individually tinned stranding. These innovations result in wring products that are ideal for the marine and mobile applications.
Ancor’s complete line of wire includes a variety of sizes and applications and every color recommended by ABYC standards. In addition, Ancor offers a full range of terminals, connectors, and wire management tools for any wiring project.
Ancor’s innovative line of NMEA 2000 cables and connectors feature unique color coding to simplify NMEA 2000 networking.
Ancor is dedicated to not just providing products, but providing innovative solutions for marine and mobile electrical projects.
Can I use regular wire for my boat?
Using the wrong type of wire can cost you more in the long run. Insist on Marine Grade® Boat Cable by Ancor. It is UL approved for the corrosive marine environment and charter boat service. Marine Grade Boat Cable is specially designed to exceed all test standards for cold bend, moisture and oil resistance, heat shock, and flammability. This ensures the safest, easiest to install, longest lasting, and ultimately the least expensive electrical system you can buy. Only Ancor offers a complete line of Marine Grade Boat Cable for every need. “Can I use ‘regular wire’ for my boat?” The answer to this common question is a qualified "yes." However, caution is advised and the installer must understand the circumstances in which SAE (Society of Automotive Engineering) J378, J1127 or J1128 wire can, and can not be used. Keep in mind that these wires are designed for "surface vehicles," not for the special requirements of the marine industry. Even if tinned copper, they should not be run in bilge spaces or other areas subject to moisture from spray or dripping. They should not be run in engine spaces unless marked “oil resistant” and “75°C”. They should not be used in applications that were subjected to vibration or frequent flexing and must never be used for 110-volt applications. For safety, use only wire which is marked with size, type, and temperature rating. Most importantly, SAE wire is up to 12% smaller than AWG Boat Cable which means that, in many applications, larger gauge wire must be used to stay within the voltage drop limits recommended by experts. The wire charts found in “Chapman’s Piloting” and other publications are all for “AWG” wire like Ancor, not “SAE” type wire.
What makes Blue Sea Systems’ marine fuses and fuse blocks unique?
Best Practices and ABYC standards state that every positive wire on the boat outside the engine starting circuit must have circuit protection. When excessive current flows in an electrical circuit, wire insulation can melt and possibly start fire
Circuit breakers and fuses protect the wire in electrical circuits. Blue Sea Systems' extensive selection of circuit breakers, fuses, fuse holders, and fuse blocks gives boaters a range of choices for main and branch circuit protection. To help select the right size wire and proper fuse or circuit breaker, Blue Sea Systems offers our Circuit Wizard
The demand for ignition-protected circuit protection has increased. Blue Sea Systems Safety and SafetyHub Fuse Blocks are specifically designed for use in environments with explosive fumes, such as an engine room or fuel storage locker.
What are some of the key features of Blue Sea Systems’ battery switches?
Battery management is central to the safe operation of a boat or vehicle. A battery switch is required by ABYC in every boat with a battery over 800 Cold Cranking Amps (CCA). This requirement exists so the potentially destructive energy in the batteries can be isolated in the event of a fire.
With involvement on the American Boating Yacht Council (ABYC) Electrical Component Project Committee, Blue Sea Systems is close to the source of standards for battery switches. The company's participation in the process means quick response when the standards and needs of boaters change.
What are the key features of the Blue Sea Systems 6-position water-resistant circuit breaker switch panel?
- Illuminated 15A circuit breakers provide switching, “ON” indication, and overcurrent protection
- Industry-standard sizes and mounting allow these panels to be easily retrofitted in an existing application
- Polycarbonate/ABS panel surface is UV-stabilized, flame retardant, and will not corrode
- Silicon breaker boots and gasket protects against water ingress
- Low profile makes it easy to install in tight spaces
- Fast-on circuit breaker connectors make it quick to wire
- Two-wire connection for powering all panels is simple and requires #10 ring terminals. Terminals screw to bus bars for secure connections
- Set of 15 square format circuit labels are included, and are easy to replace. Additional standard or custom labels are available through Blue Sea Systems
