30 amp to 15 amp plug for shore power

Postby tsmitherman » Tue Oct 16, 2012 5:24 am

I'm trying to hook up a small fan and/or heater for the boat, to be powered by the standard marina shore power 30 amp receptacle. I have a 15 amp, 3 wqy splitter with a built-in GFI, but I need to convert from the 30 amp marina receptacle to the 15 amp. (30 amp male on one end, 15 amp female on the other).

I bought what I thought was the adapter I needed from Lowes, but the 30 amp side is not the "locking" type, which is used for shore power. When I started looking, I find various types of 30 amp plugs, some with flat prongs, some with round prongs, some with twisting "locking" prongs, and some with 4 prongs! There are even some labeled for "generators". :? :?

Can somebody direct me to the adapter I need, or the correct name of the male 30 amp plug I need for marina use?

The admiral is balking on my November boat trip unless I figure a way to hook up a small heater on the boat!

That is kinda pricey, Bill. :shock:

What I need is something like that, but with the male/female ends reversed. I need the 30amp male plug to plug into the shoreside box, then a female 15a on the other end to plug my 3 way splitter and regular extension cord into.

Thanks Paul.
The camper style 30 amp adapter is what I bought from Lowes - two straight flat prongs and rounded grounding prong. Those are different from the "twist-lock" style used in marinas. The links you gave did show a "generator" plug that looks like it might be the same as the marina type, but I'm not sure if they are exactly the same or not.

Hopefully someone with camping and boating experience can tell me if they are the same.

Tom; Think this is what you need. Should be available at most marine suppliers.

That Marinco unit will work, thanks Doug and Bill. I'm not sure it will work in my budget, though. :(

I think I've got enough info now though to at least go looking and be able to tell someone what I need.

I printed off the prong arrangement for the 30a plug from Marinco, and I'll shop at the big box and camper places locally to see if the ones marketed for generators are the same. They seem to be priced much more reasonably.

Thanks again for all the help. This forum is great when you need info.

Here is a link to Marinco's pdf catalog. I have found the images helpful in sorting this stuff out. Look at page 18 and following pages - http://www.marinco.com/files/Global%20Marine_catalog.pdf

I am needing a 30A to 50A adapter (121A) as I am finding some marinas only have 50A outlets BUT having trouble trying to justify spending over $100 on a short piece of cable! They sure are proud of these things.
