Re: [Amel Yacht Owners] Shore power plug questions.


Bill & Judy Rouse <yahoogroups@...>
 

Alex,

I am not sure that the shore power is only rated for 230VAC 50htz 16 amps. I think it is designed for 32 amps, but maybe less with 220VAC 60htz and/or use of a transformer.

I am not an electrician, but I believe that the maximum amperage is also determined by some other things including any transformer in-line and whether you are using USA style 220VAC 60htz with two 110VAC 60htz hot wires.

To answer this question with clarity I think you will need a certified marine electrician. It might be worth paying one for a few hours to check the AC systems on your boat. But, if you hire one make sure he is very familiar with marine 230VAC 50htz.  Where you are may make this difficult.

Good morning Eric, Alan,

I am not concerned about tripping a 16 Amp dock breaker.

I am concerned about my shore power cable being too small to pull for example 25 Amp out of a 32 Amp dock outlet.

Example, in 50 hertz countries if I use my Scuba compressor and my washing machine, plus some outlet, I will draw 25 Amps (5600 Watt) (this is what I measured with the Blue Sea last week while I was using my genset).

So if the shore power cable is only able to sustain 16 Amp, I am 50% above and don’t want to have an overheating and possibly get it on fire.

Going through your reply Alan, so if I understand correctly, you say the “shore power cable” coming from the boat is ok for 32 Amp. But the small extension I have is not, so I just need to replace that (with a thicker cable)?

Thanks for all of your reply.
Sincerely, Alexandre

That's true but if you try to draw 30A from a
dock outlet that is only rated to 16A, you will trip the
breaker on the dock..If you run too many 220V items at the
same time you can easily exceed 16A.....I know, I've
done it !
