The ABYC recommends wire conductors of at least 16-AWG (gauge) for lights and other similar equipment. That’s minimum, and heavier gauge isn’t much more expensive — and generally no more trouble to install. We suggest you use 12- or 14-AWG to minimize your voltage drops, or more if the manufacturer suggests it.
What is an outboard wiring harness?
Boat Wiring Harness Market: Introduction
A boat wiring harness is an assembly of wires or electric cables that is used to transmit electric power or a signal.
Marine-grade wire is more expensive than standard SAE automotive wire, but it’s much better suited for boats, with more copper conductor in a given gauge size, and better resistance to chafe and heat.

What is the difference between marine wire and regular wire?
Beyond being tinned, marine cable is larger than say automotive cable at the same size. So, 6 AWG marine cable contains more copper than 6 AWG automotive cable. The more copper, the better the current carrying capacity of the cable. Marine cable also carries a pliable and durable PVC jacket.
What is marine wire called?
Primary Marine Wire, commonly called primary wire or boat wire, is electrical wire designed for use in the harsh marine environment.
Can you use automotive wire on boats?
In general, automotive wire can be used on boats, assuming that it is SAE (Society of Automotive Engineering) J378, J1127 or J1128 rated, but it is not recommended. Marine-specific wire is unique in a few ways. Most importantly, marine wire is larger for a given gauge size, up to 12% larger in some sizes.
What size wire should I use for a bilge pump?
When installing your pump, 14-gauge wire should be used. However, if your installation is over 20′ from the battery source, the wire size should be increased to 12 gauge. Using a wire that is too small causes undesirable heat in the wires and results in a voltage drop and lower performance of the pump.
What is tinned marine wire?
Tinned copper stranding for maximum protection against corrosion, electrolysis and resists fatigue due to vibration and flexing. Rated at 600 volts and 105-Degree C , the heavy duty insulation is resistant to heat and abrasion. Exceeds all UL 1426, US Coast Guard Charter Boat and ABYC standards.
Certainly, but you shouldn’t exceed the current capacity of the smaller conductor. In this case, the 14 gauge wire, which in the US at 120V is typically rated at 15 Amps. (12 AWG is rated at 20 Amps.)
Can 14 gauge handle 20 amps?
NO.14 gauge is prohibited from use in any section of a 20 amp circuit. You need to use 12 gauge wire for 20 amp circuits. This is for safety reasons.
Is it OK to use 12 gauge wire on a 15 amp circuit?
However, 12-gauge wire is acceptable on both 15- and 20-amp circuits, so some electricians use it exclusively when wiring a house. This avoids the potential for mixing wire gauges in future repairs or additions, which is prohibited by the National Electric Code because it’s a fire hazard.
How far can you run 14 gauge wire on a 15 amp circuit?
For a 120-volt circuit, you can run up to 50 feet of #14 AWG cable without exceeding 3% Voltage Drop on a 15 amp circuit.
How many amps will a 14 gauge wire carry?

Can 14 AWG handle 30 amps?
No, 14 gage wire uses a 15 amp breaker. A 30 amp breaker will allow twice the current a 14 gage wire can handle and can overheat the wire – fire hazard.
A 15-amp circuit is usually served by 14-gauge wire and is protected by a 15-amp circuit breaker or fuse. A 20-amp circuit, protected by a 20-amp breaker or fuse, must be served by 12-gauge or 10-gauge wire.
What happens if wire gauge is too big?
If a wire gauge is “too big” then it is a lot more expensive and is harder to bend, as well as more difficult to attach with wire nuts or to switches. Other than that, not much of anything.
What happens if you put a 20 amp outlet on a 15 amp circuit?
If your question is “can I connect a receptacle rated for 20 amps to a circuit designed for 15 amps?”, the answer is yes, because the receptacle can handle more current than the circuit is rated for. If you exceed 15 amps, the breaker will blow, and protect the receptacle.
How do you tell if a circuit is 15 or 20 amp?
Can I put a 20 amp breaker on a 15 amp circuit?
You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire. To help you understand why this is so dangerous, you need to know what the circuit breaker is for.
