Whats the best and cheapest way to hook up to 20 amp service when I already have 30 amp cords? I havn't been in to West Marine or Boat US yet, but looking on websites looks like a 20A to 30A pig tail is $70-$99. I could buy a whole 30AMP cord for less than that...
thanks

Does the shorepower outlet only supply 20 amp or is the boat electrical load only rated at 20 amp?

no, my boat is 30amp. The electrical box at Beacon Cove is 20amps.

You shouldn't have a problem with a 30 amp rated cord. If the shorepower was 30 amp and you are using a 20 amp rated cord then it would be an issue. You may just keep tripping the shore breaker if you turn on too many items (ie: air conditioning).

Make sure the polarity matches (most boat panels have a light to indicate reverse polarity hookups.)

the problem arrises because the 30AMP plug is slightly larger than 20AMP plugs.
(where I plug into the power box..)

If you have an extra cord, cut the male end off and just buy the 20amp male end. Other than that your stuck with buying the adapter.

I hear a lot of beacon cove is 20amp. I'm on m row and its 30amp. Also the adapter is easier to steal.

yes the standard plug is a bit cheaper.. but not H20 protected.
I still am amazed at how much they cost.

my cord is a little old anyways, I may just buy a 20Amp Male plug, chop off the existing 30A and replace it.

I just built another 30amp cord with a male ended cord and a female plug end. Just went out and bought the waterproof boot and bingo.....30 foot cord. Now I can leave the 25 and 50 footers on the boat and leave that one at the slip. Check it out if you want. M-12.

I have a 20 -30 amp adapter I use to need at Beacon Cove,
Make offer. I beleive it was originally purchased from Beacon Cove.

All you will have to do is plug your 30 Amp shore power into the adapter cord that is a bout a foot long. That way you don't have to mess up your shore power cord.

Once you steal the adapter, head over to M12 for an unguarded 30' cord to attach it to...
