Pigtail Adapter: 30A to household 15a plug

Does anyone have any experience using a 30 amp to 125v standard plug pigtail adapter ... To plug into a regular household extension cord. I frequent a family member's dock that does not have standard marina-grade shorepower. Any caveats?

Re: Pigtail Adapter: 30A to household 15a plug

if it is a 30 amp circuit and you plug in a 15 amp cord you take a chance of burning up the cord before the 30 breaker will trip. yes I know it is done but that does not make it safe. breakers are to protect the wires. so if the breaker is 30 amps then the wire should be able to take 30 amps. you could have a portable 15 amp breaker box that plugs into the 30 receptacle before the 15 amp cord.

Re: Pigtail Adapter: 30A to household 15a plug

I'd also suggest using a test light and confirming the ground (especially) on the family wiring. An awful lot of casual "extending" on home wiring is done without ground, or with hot and neutral reversed. It might be worthwhile adding a box to your pigtail, with a GFI, 15 amp breaker, etc. so you've got a robust adapter that can be used anywhere. Or not, as suits your time and wallet.

Is this what you're looking for? I have used one when the boat was hauled.

I think I see what you are saying. Your boat has the 30a shore power receptical, but the only thing availible at the dock is 15a house power?

I think I would be more tempted to run off of the batteries and use the house power to keep them charged

Re: Pigtail Adapter: 30A to household 15a plug

I don't think you will have a problem. You won't be able to run a/c while plugged in and you may have a problem running a microwave, especially if the battery charger is on. What would happen in that case is the breaker in the house will click off and need to be reset. No big problem, just a hassle. If you find that a problem, convince the family to install a proper 30 amp service if they want your company!

I used a 125V to 30A pigtail to plug in my power cord every spring on the hard in Rock Hall as the majority of electrical service in the "boat parking" area was of the 125V type. Of course the 125V outlet was protected by a 20amp breaker. Common stuff from what I've seen.

Re: Pigtail Adapter: 30A to household 15a plug

We have a solid plug adaptor (not a pigtail) to plug our 30A shore power cord into a 120V AC outlet... Only issue is that its a bit long and may prevent the box from closing - sometimes we have to support the cord with some lashing or it pulls itself out.

Just remember your load limitations...

Re: Pigtail Adapter: 30A to household 15a plug

I go the other way 'round. Every day I plug my 110-volt, 10.5 amp, 1.25 hp air compressor into 30 amp shorepower using a 16-gauge extension cord. Have done for almost 19 years. Never a problem.

Correct. My boat is pretty modest load wise. No a/c or microwaves etc. I mostly want to keep my batteries topped off and run some small power tools. I have a smart charger on board.
