There are certain important precautions you will want to follow in order to preserve the internal circuits and systems in your boat. ... read more
Step 1: Choosing a Wire
- Identity where the current flow is located in your circuits.
- Choose the circuit type.
- Non-critical: consitutes at least a 10% voltage drop, which covers all general appliances, general lighting, etc.
- Critical: at least a 3% voltage drop, which covers navigation lights, electronics, etc.
- Determine the circuit length.
- Circuit length: the length of the negative wire combined with the length of the positive wire.
- Intersect the current flow with the circuit length in order to calculate the wire size that will work best for you.
Step 2: Choosing Fuses and Fuse Amperages
- Choose the fuse while simultaneously referring to the AWG wire size that you selected from Step 1.
- There are four different fuse amperages to choose from:
- Single Wire, Outside Engine Room.
- Single Wire, Inside Engine Room.
- Bundled Wire, Outside Engine Room.
- Bundled Wire, Inside Engine Room.
Step 3: Choosing a Fuse Holder
- Refer to the fuses and fuse amperages you selected from Step 2 in order to determine which fuse holder/fuse block will work best for you.
- Two environmental standpoints to consider depending on which fuse holder you choose:
- Ignition Protection: a mandatory choice when there is a possibility of flammable vapors collecting.
- Ingress Protection: shields the fuse holder from humidity and other environmental features.
- Inline Fuse Holder Vs. Fuse Block
- Inline fuse holders are compact and hold single low-amperage fuses.
- Fuse blocks attach to solid surfaces and can hold either single or multiple fuses.
