In a boat, electricity is stored in one or more batteries. They can hold an enormous amount of energy, capable of pushing hundreds, or even a thousand amps more than your entire house uses … so care must be taken, and proper circuit protection should not be ignored.
Greatly generalizing the topic here, but you usually run into two types of batteries in the size of boat we deal with:. Batteries have a positive and negative. For current to flow which does the work a complete circuit must be made from positive back to the negative.
A normal battery might have AH amp hours of capacity. Meaning it can run a 1A load for 70 to 80 hours, or a 10A load for 7 to 8 hours before it is discharged. In nearly all cases your boat wiring system should have a marine grade main battery disconnect switch. This allows you to open the switch turning everything off at once. Both battery positives are ran through this switch, and you can use it to select which battery you want to output, similar to an A-B switch.
How To Wire (or re-wire) a boat
But a BOTH marine battery switch also allows you to parallel both batteries. The both setting might be used when you are running your engine and want to charge both batteries from the alternator, or if you need to parallel the batteries in an emergency to help start your engine if your start battery becomes too depleted. I allows your house and start battery to remain isolated except for emergency conditions. Used to shutoff everything and prevent trickle charges from draining your battery. This way, even if your battery switch is off, if your boat starts filling with water the pump will still kick on.
Notice the fuse shown — this needs to be circuit protected with an inline fuse like this one. We have an in depth article here on how to wire a bilge pump … check that out as well for more details.
It looks great and using your tutorials I have been able to rewire my 10 year old center console. The support I received from New Wire Marine went above and beyond. Thank You! The next step is to get the power from the house battery up to the switch panel where we can use it to do some good.
Two conductors — a positive from the battery switch with a fuse and a negative from the ganged together battery negatives should be ran to where the central switch panel is. You should use marine grade primary wire for this. This is sometimes a long wiring run on a boat.Display Options.

Watts and Amperage This will help you consider the circuits to be served by the Sub-Panel including general purpose electrical outlets and any special equipment which will be needed. Special Considerations: Large Volt Loads such as Welders, Air Conditioners, Motors, Well Pumps and the like may require larger size wire and conduit to provide the necessary current this equipment requires. Be sure to list all the label requirements and manufacturers specifications.
How to Install and Wire a Sub-Panel
Long Distances from the power source will produce Voltage Drop, especially over feet. I fed this sub panel with 10 UF cable. From this sub panel, I am feeding 2 — 20 amp circuits with 14 wire. With nothing but the fluorescent lighting on, I pull about 2. When I turn on my shop vac however, I am pulling about 11 amps of current, and my measured voltage on this circuit drops to volts.
This causes my fluorescent light bulbs to cycle on and off. Is the voltage drop enough to cause this issue, or am I missing something?
When planning the wire size for a sub panel, or any panel for that matter, it is important to factor in the length of the distance to the panel from the source, and the amperage of the sub panel. The circuit loads placed upon the sub panel will determine the size of the sub panel as well. So basically, everything starts with planning the load that will be placed on the sub panel, and then we calculate the wire size feeding the sub panel based upon the distance.
It is also important to factor in any electric motors that may be used due to the starting load which will effect the amperage and the voltage. The Non-Contact Electrical Tester This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring.

The Wire Stripper and Wire Cutter My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses: The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.
The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use. Estimated Time: Depends on personal level experience, ability to work with tools, install electrical circuit wiring, and the available access to the project area. Working in an electric panel is dangerous due to arc flash hazards and the possibility of electric shock. Electrical Wiring Parts and Materials: Electrical parts and materials for circuit wiring projects should be approved for the specific project and compliant with local and national electrical codes.
Electrical Codes and Inspections: Installing additional electrical circuit wiring should be done according to local and national electrical codes with a permit and be inspected.At Circle Track we have the luxury of meeting teams at all levels of racing from all across the country. Many of you are wizards with a welder and fabricate anything. Many of you can rebuild a race engine with your eyes closed and practically tune a carburetor while the car is still running laps under caution.
And many of you out there can run crossweight calculations in your head like the rest of us say our ABCs. But what we haven't heard is many racers claim to be electrical experts.
Don't get us wrong, we know plenty of you are capable, it's just that very few racers are either comfortable working with electrical systems or actually enjoy it. Still, it's important to be able to have confidence that you can wire your race car correctly so that you aren't wasting time chasing those annoying electrical gremlins that usually seem to pop up at the worst possible time.
For a little help we caught up with someone who actually calls himself a wiring and electrical-systems specialist. Rick Elgin owns RaceWire Technologies, and he spends his days wiring practically everything on circle track race cars, drag cars, hot rods, and anything else with a battery and a starter. While there he not only learned all the tricks, he also helped develop a few of them, and now he's applying his expertise to help Saturday night racers.
Elgin is based out of the Charlotte, North Carolina, area and travels to the surrounding states to wire cars for racers in their shops. For this story we met him at the shop of Chris Ferguson Motorsports in Mt. Holly, North Carolina. Ferguson races Dirt Late Models and like most Saturday night racers, his program is a small operation and most of his help comes from his family. They could handle wiring the car themselves but every dirt car lives a hard life between racing and the wash pit, and they wanted to make sure they had the most dependable system possible to avoid the potential of electrical problems costing Ferguson potential victories.
This story isn't going to attempt to show you every step of wiring a car front to back. Every car is a little different, and honestly, that would be a pretty boring read. Instead, we're going to pass along tips Elgin provided us and show you what he uses and why.
For example, Elgin says he often helps racers fix problems with existing systems, and the problem he sees most often is poor grounding of electrical circuits. Many racers will use several grounds—maybe one for the starter, one for the gauges, and another for the ignition box—but if one ground isn't working as effectively as it should that extra electricity can bleed back into other circuits.
To eliminate this Elgin prefers to always run a tracer wire to each ground, and often back to the battery, to make sure everything stays equalized and is grounded optimally.
We've got lots more for you, so read on. Point 1: Chris Ferguson's Warrior DLM chassis that Elgin is working on is brand new with no old wiring to pull off, but Elgin did save some samples from previous projects for us.With brilliant design and construction, our revolutionary integrated race car wiring system can be adapted for any application.
