Surveying Electrical Systems - Webinar

Former ABYC Education VP Ed Sherman comes out of retirement and will walk you through an electrical system survey. You’ll see first hand some of the things that can be the difference between a safe system and one that could spell disaster. He will focus on wire support and chafe protection, proper wire types, overcurrent protection, wire terminations, AC and DC power sources and grounding, ignition protection, and more!

i'm so glad to see the online certification classes, as trip costs pose a barrier to registration

These videos are very, very valuable to old timers and apprentices alike. Access to online educational opportunities is by far the best benefit of ABYC membership.

I was genuinely and pleasantly surprised by how much I already knew about the subjects covered in E'd presentation, which goes someway to prove how continued learning and experience gained over my twenty plus years working in the marine industry has been a priceless investment of effort, time and money. But I was also reminded about how much you can forget and take for granted, and how we each must realise that some practises out there in the marine environment can be deadly and you mustn't take things for granted. Ed's presentation was both informative and entertaining, his knowledge of the subjects covered was plain to see.
Many Thanks

Heat shrink for labeling, 40 inch and 72 inch wire length rule, AC 10 ft rule, self limiting devices, use of thermal cameras basics, 4 wires a stud rule. I was very satisfied with the presentation, visuals, and examples used.

I will start by saying I am not an expert. At 19:12 you mention that fusing alternators is a waste of money as long as the cable is sized correctly since the alternator is a self limiting device. I was under the impression that the circuit protection on an alternator circuit is to protect over current from the battery and are placed there if the fuse on the battery was too large to safely protect the alternator cable. Is my understanding wrong? Thank you posting this video. It provided a lot of useful information.

Yes, alternator installation manuals describe fusing as close as possible to the battery, since the main reason for fusing is to protect the wire from backfeeding from the battery that might happen if the wire were shorted (even with engine off). On my boat the alternator feed presently comes off the main unfused starter wire, so the fuse for the alternator wire is close to the point at which it attaches to the source of battery power at the starter, even though normal flow is reversed when engine is on. As mentioned, you don't need to fuse for the alternator source, but that's not the point.

I'll never forget the survey I needed for insurance- $600 and the report specified- "Diesel generator in tip-top condition". The only issue was my boat didn't have a Diesel generator and in fact no Diesel fuel on board. Pay the crooks for the report to satisfy insurance underwriters- but never EVER trust a survey as proof of a boats seaworthy condition. Half of these surveyors work as surveyors because they couldn't distinguish the business end of a screwdriver!

Old man with tongue 👅 outside make me laugh 😆, but very informative video. Tnx Ed and guy who talks 1000 words per minute! 🙃
