What Gauge Wire For 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 gauge wire should I use on my boat?

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.

How many amps does a 12 volt bilge pump draw?

12 volt DC – 2.1 amp draw. Hose outlet suits 20mm hose. Compact submersible electric pumps for use as bilge or bait pumps. 500 GPH – 31 Litres per minute.

How many amps does a bilge pump take?

Product Specs Amperage 3.7 Capacity 1100 Gallons per Hour Diameter 1 and 1 1/8 Inches Voltage 12 Volts Warranty Details Three Year Limited Warranty; Contact Manufacturer For Details.

Should bilge pump be wired directly to battery?

Connect to the battery When you turn the power off to leave the boat unattended, you don’t want to turn off the bilge pump. Connect an automatic bilge pump directly to the battery, not through the distribution panel.

What is the difference between marine wire and regular wire?

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. The fine stranding makes the wire very flexible, allowing it to better survive in a moving, vibrating boat, while the tinned strands provide additional corrosion protection.

Can I mix 12 gauge and 14 gauge wire?

Originally Answered: Can I mix 12 and 14 gauge wire? The 12 gauge can carry more current, therefore; you must not use 14 gauge in place of 12 gauge, but you can use 12 gauge in place of 14 gauge, but 12 gauge is larger.

How much does a bilge pump draw?

According to Rule’s technical documents, the pump will put out 1,620gph against a 1m (3ft 4in) head or 1,300gph against 2m (6ft 8in). In other words, you lose around 20 percent of your pump’s output when it has to lift the bilge water more than 3ft and 30 percent at 6ft 8in.

How many amps does a Rule 2000 bilge pump draw?

Current Draw: 8.4 Amps.

How many amps does a livewell pump draw?

A typical 800gph live well pump can draw 3 amps. so 3amps times 1 hour = 3ah. At 6 hours it would be 18 ah out of your reserve capacity. If you are seeing 11 volts, your battery is dead or severely undercharged.

What kind of battery do I need for a bilge pump?

Most people go with sealed lead-acid (SLA) batteries because they are less expensive and waterproof, but they are heavier than some other options. Some folks would use a 5 amp/hour 12 V SLA for that pump, but I would go with a 3.3 Ah battery like this Werker: http://www.batteriesplus.com/product/32 r/12V.

Is marine grade wire needed?

This will eventually lead to cracking of the insulation which will let moisture in. Without the tinning we talked about before, these cracks will lead to more corrosion. This is why it is essential to only use marine cable on your boat.

What type of wire is marine grade?

Well being marine grade means the power cable or speaker wire has been treated with a coating to prevent oxidation, usually tin. Tinned copper will not tarnish or oxidize like bare copper.

How do I know if my wire is marine grade?

the copper color of the blue cable. The silver color is “tinning,” which although not a Standards requirement, we often see on marine graded wire. The tinning is to minimize the effects of corrosion to the individual strands.

Should I use 14 or 12 gauge wire?

As long as you don’t put too many lights on the light circuit, you can usually control that circuit with a 15-amp breaker, as well as wire it with a 14-gauge wire. On the other hand, an outlet circuit controlled by a 20-amp breaker requires a 12-gauge wire.

Which is thicker 12 or 14 gauge wire?

Twelve gauge is about the thickness of a nickel, and 14-gauge is about the thickness of a dime. Also, look at the breaker for the circuit in question to see if it’s a 15-amp or a 20-amp breaker. A 20-amp circuit requires wire that’s 12-gauge or larger.

What happens if you use 14 gauge wire on a 20 amp circuit?

I would say 14 gauge wire anywhere on a 20 amp circuit is not OK. The purpose of the breaker is to cut off power before the wiring overheats. If you plug in several devices on an outlet that total 20 amps, you will exceed the safe working capacity of the 14 gauge wire without tripping the breaker.

Can I add a float switch to a bilge pump?

The addition of a float switch to a bilge pump circuit allows the bilge pump to come on automatically once the water in the boat reaches a certain level. This ensures that even if there is nobody on the boat to turn on the bilge pump, it will still pump water out of the boat.
