Almost every piece of electrical equipment we use on a boat will have a label (or a manual) that tells us its demand for amperage, its output in watts, or both. As for the term power, it’s best described as “the rate of doing work or expending energy,” and it’s measured in watts. Along the way, electrical gear on the boat will take power from the current flow in that circuit and use it to show us electronic charts, pump the bilge, and perform all sorts of other chores for us. In the case of electricity on a boat, think of that circuit leaving and returning to the source of power, which could be a battery or the shore-power pedestal on the dock. We can think of it as a route with a starting and finishing point at the same place, like a racecourse with the same starting and finishing line. Now, it’s worth considering the definition of circuit, too. Amperes express the volume or number of electrons that pass a given point in a circuit in one second.
The words that apply to this flow are ampere, amps, and amperage. Electrical current, or current flow, is sometimes described as the ‘flow of electrons’ within a circuit. The reason is simple: If there is no potential difference in the circuit, there can be no current flow. As I’ve gained more experience working with electrical systems over the years I’ve found myself embracing the ‘potential difference’ definition. But another definition of voltage describes it as a difference of potential from one point in the circuit to another. The Major Players – Volts, Amps, Watts, and Ohms One of the primary players in this game, voltage, or volts, can be thought of as the pressure or force available in an electrical circuit. Let’s get started with some marine DC basics so that you can do some troubleshooting and make safe, reliable electrical installations on your own. Electricity operates in predictable ways, even if it is invisible, and learning to work with it will make you happier and safer on the water. For people just getting into boating, or for those who have been boating for a while but have managed to avoid the electrical side of things, the 12-volt DC (direct current) systems aboard most boats don’t have to be daunting. The records of each quality control stage of the production process are very strict, so you can buy with confidence.The back of a wiring panel can look pretty daunting, but remember, you're only troubleshooting one circuit at a time.
Every step from purchasing the equipment to the product delivery inspection has been checked and registered.It has a nice appearance and is small and portable, providing you with a good using experience. It can be installed on any flat surface, providing higher air flow, lower amperage consumption and quieter operation than standard fan. The Air Blower fan is easy to use and install.These fans use special front and rear shaft seals and motor housings to extend their service life. The sealed motor shaft can prevent moisture and is designed for efficient operation and high efficiency. The fan is equipped with a five-leaf fan to maximize airflow and efficiency. It gives you quality assurance and longer service life, so you can buy it with confidence. It is lightweight, firm, precise, safe and durable, and not easy to break. The bilge air blower is composed of ABS shell + copper motor core.
