Not professional advice
HarborWatt is not a licensed marine electrician, surveyor, or engineer for your specific vessel. Our guides describe general principles and common practices. Electrical work on a boat carries real risks of fire, shock, and damage. For any work you are unsure about, especially anything involving AC shore power, hire a qualified professional or an ABYC-certified installer.
Your responsibility
Every boat is different. Wire sizes, fuse ratings, and component choices depend on your exact setup. Always follow the instructions and ratings supplied by your equipment manufacturer, and verify local regulations that apply to your vessel.
Accuracy
We aim for accurate, current information, but we cannot guarantee that every figure or recommendation fits your situation. Specifications change, and errors can slip through. Confirm critical details before you buy or build.
