Default Convert 220 outlet to 110?

Good morning,
Have an electrical question for you guys. I have a 220 4 prong outlet on my boat lift. I believe it is an L14 style. Are there any adapters that will convert the 220 into a standard 110v household outlet? I need the 220 outlet to remain the same as the lift plug is matched to it. I would like to be able to plug the boat in without running an extension cord across the dock. I wish the electrician had wired an extra 110 outlet for this purpose but he didnt.

Thanks

Is there a neutral in the feed? If you can see the incoming wires....how many are you working with, should either be 3 or 4.

If you have a neutral, you can use either of the hot feeds to get you 110VAC... Your best bet is to fire an electrician to check it and install a weatherproof outlet.

There are ways to rewire it, but the proper way would be to add a load box and split the feed there. Then you would have separate breakers for the 110 and 220.

Fire instead of hire!

I'll probably get a lot of crap on here, but if you have enough mechanical & electrical knowledge go take a decent size boat 100 miles out to fish and deal with the problems that may occur underway, then one should be able to learn and understand how to correctly (and safely) wire up a 110v GFCI outlet from a box with 220v in it. Maybe it's better to think of the inverse: if you can't learn how to correctly...

The plug KBH posted are used at marina's everywhere.

I am not sure about the electrical code where the OPP is, but in New York, while you can split one 230vac feed in two separate 115vac circuits, you cannot split a 230vac circuit into both a 230vac circuit and one or two 115vac circuits from the same feed without it going to a sub-panel and having all 3 or 4 of the lines on that sub-panel on their own circuit breakers.
For the OP, just get the plug in splitter like KBH shows you - rewiring is going to be very expensive.

Where do you live that you are only getting 220V instead of 240?

OP- if you're asking, then I would not recommend you open the box and "delete" 1/2 of your feed.
I'm not an electrician, but consider it common practice when situ calls for it.
A lot of 220's are just two 110's to the same circuit/breaker.
Taking one of those off, leaves you with 110.
If you don't understand how to "take it off", then see first sentence and please heed comment below.
Call an electrician.

Water and electricity cause so many deaths each year. Not something to experiment with. Call a professional. The cost is nothing compared to a bad result.

Also should have a GFCI in the circuit.

Let's simplify.

If you have a 4 prong outlet, you should have 2 hots, a neutral and a ground.

220v is derived without a neutral. It is the addition of 2-110V "Hots" together.

110V is derived from one "hot" and a neutral.

If the lift only requires 220V and does not require 110V for controls, relays or anything else, then the electrician may have used a 4 wire plug but only ran 3 wires, 2 hots and a ground. The only way to know would be to meter them out or look in the box and count the wires.

If there is a neutral wired to the the 4 prong outlet, you can use a splitter cord to turn it into 2 110V circuits. If there is not a neutral, (only 3 wires ran from the panel rather than 4) you will not be able to split 110v off the 4 wire plug. You can however purchase a Step down transformer that will plug in and convert your 220V to 110V. Like this https://www.110220volts.com/ac-3000w...iABEgKzmPD_BwE

Or alternatively, you could pull a neutral from the panel to get your 110V using one of the existing hots. If this is all foreign to you, then you should probably hire an electrician.

Not sure if this was sarcasm or ?

Basically the term is used interchangeably in the US.

Or, maybe OP is from Alabama, and they haven't gotten around to upgrading yet?

Thanks. Not looking to change anything with the outlet. The lift is 220 and plugs into it. I was hoping there was an easy solution to be able to run the 110v battery charger off of it when the lift is not in use. I will check into whether or not there is a neutral.

You really need to run a separate circuit from the breaker box on your dock to a separate 115V GFCI outlet.

Thanks, that is what I am going to do.

Is it a 3 wire outlet or 4 wire?

This is not intended to be used as a permanent connector. The OP wishes to use the 110v for a battery charger presumably while he is away from the boat. The whole configuration would be subject to moisture. The battery charger wouldn’t be weatherproof at the point it connects to the splitter.

If the feed to the outlet was done properly with 4 conductor wire, then it should have L1, L2, neutral and ground. If so, then the plug will work.

If it were me, I'd prefer the sub panel route to have a dedicated 110VAC source readily available.
