For the last several weeks, I have been chasing a problem that has been causing me to lose sleep at night. Every time I think I have it fixed, it seems like another issue pops up and I’m back to square one. I finally conquered it by fixing a ground and using isolated power with a heavier guage wire. here
After many decades of troubleshooting and repairing boat wiring issues, I’ve become pretty darn good at figuring things out. Today’s boat wiring is one of the most difficult problems you’ll run across due to requirements of the numerous accessories.
This issue got me thinking that I’m probably not the only one that has experienced these headaches. So I wanted to make a short checklist that might help you if you run into a similar issue. If you’re just getting started working on your own boat wiring, these are some rules you should certainly follow. here
A Hummingbird Model 345C depth sounder draws 380ma (from the specifications). Their installation includes a 6 foot power cable of 18ga wire. This may be fine for connecting it to a fuse block near the dash, but the cable running from the battery to the dash is going to be at least 10-12 feet long. You need to double that for the return wire. So I would go up a size to 16ga for the run from the battery to the dash. A 16 ga wire 15 feet long and 15 feet back, with a 15 amp load will have less than a 10% voltage drop. Since this wire may be powering other equipment from the in dash fuse block it would be good to make it larger than the wires from the fuse block to the equipment. Confusing? I’ll try to make it simpler. here
Use the locations of each piece to decide where to put fuse boxes, buss bars, switch panels, etc. Each of these must be close to the equipment they power, and easily accessible to be worked on. They cannot be hidden behind equipment or inaccessible panels. This may sound obvious, but I have seen some very bad installations. Also they should be where they are protected from spray or rain. more
Step 11. Fuses. How big should your fuses be? [links]
Don’t be concerned if you don’t know electrical symbols. Just make a box or circle and write in what it is, or you can use a picture of the item. As long as you understand what goes where and how they are connected it’s Ok. Remember, any 12V DC device has to have at least a positive and negative wire connected to it. Put a plus or minus next to the wire or use red for positive and black for negative. On metal boats do not use the hull as a return path. None of the wiring should be electrically connected to the hull.
Wire terminals must be used. Connections should never be a bare wire wrapped around a stud or post. This is bad practice, and can easily come loose or result in a high resistance connection. High resistance equals heat, which results in fire. [links]
To be effective, overcurrent protection devices must be installed as close as possible to the source of power for a circuit. In fact, the ABYC recommends that circuits be fused within 7" of their connection to a power source. There are some exceptions to this recommendation, notably cranking circuits (these require no protection at all), circuits that are connected directly to a battery post (in which case the 7" is extended to 72"), and cables which are housed in a sheath (in which case the 7" is extended to 40"), but in general the point needs to be made: every circuit should be provided with a properly sized overcurrent protection device at the circuit's connection to a power source. If you've got a bunch of cables hot-wired to your batteries with no overcurrent protection, not only are these circuits not recommended, but you're also inviting a fire!
It makes no sense to install high-quality, marine-rated electrical and electronic equipment on boats without at the same time using high quality, marine-rated cables and terminals to power the equipment. In the marine environment, "high-quality, marine-rated" is determined by the following:
There are two columns in the ampacity table-one for use outside engine spaces, and one for use inside engine spaces. The reason for this is that engine rooms are usually hot. Even before a circuit is turned on, a cable is warm. In these conditions it takes less current flow to bring the cable to a dangerous temperature than it does in a colder environment; hence, the de- rating in high ambient temperatures. If any part of a circuit runs through engine room spaces, the lower ampacity rating is used to determine the proper overcurrent protection for that circuit.
* Current (amps) determined by adding the total amps on a circuit. here
Fuses and circuit breakers, which collectively are known as overcurrent protection devices, are the primary defense against electrical fires. To be effective, they must meet two conditions: they must be properly sized for their circuit, and they must be placed as close as possible to the electrical source for the circuit.
Overcurrent protection is a frequently misunderstood subject. Its need arises from the fact that if a short circuit develops in onboard wiring, high current flows occur, generating heat and causing cables to melt down. If the short is a serious one (a "dead short"), cables can burst into flames, setting fire to the boat and its surroundings. Electrical fires are among the most common fires onboard.
When you’re looking to upgrade your boat switch panels , Consider Sea Dog’s Battery Test Switch with Gauge and Lighter . In a compact 6.5” x 4.5” space it provides toggles to test anchor, running and cabin lights. There is an accessory lighter which is convenient for lighting grills, gas stoves, etc. When you are upgrading your circuit breaker, consider Blue Sea’s Water-Resistant Horizontal Circuit Breaker, Panel 8 Position . Designed for flybridge and open cockpit applications, the horizontal placement facilitates resetting circuit breakers when needed. Want state-of-the-art? You’ll find a switch for every electrical component onboard with Paneltronics’ Standard Panel AC/DC 19 Posiiton Circuit Breaker w/Meters and & LEDs . It shows real-time line and load usage, too.
Electrical boxes for marine craft are similar to those in residential dwellings with one key feature: They must be completely watertight and humidity and corrosion-proof. There have been improvements to the design and functionality of marine switch panels over the years. It may be time to upgrade the electrical panels in your boat. When updating or maintaining your boat’s electrical system panel, you can rely on Wholesale Marine’s selection of boat switch panels from the best marine electrical manufacturers: Sea Dog , Paneltronics, and Blue Seas .
Our boat switch panels are available in unloaded, unwired and fully wired and for a variety of number of switches. Other considerations are vertical or horizontal positioning. Many are available with circuit breakers. When you need solid advice, just ask our Customer Service Representatives. We’re boating enthusiasts like yourselves and will be glad to advise you so you can make an informed decision regarding an electrical component’s replacement or upgrade.
