Question about electrical Splitter

Sorry if this is in the wrong place or if I could not find something similar through my search.

I was wondering if there is a splitter that would allow me to plug the 30 amp male into a 30 amp female splitter and the other end of the splitter a 120 male, to plug into my home outlet. Does that exist and would it allow an ac to run in the AS.

I think this is what your looking for.

It's a 30 to 15A adapter, and I'm not sure if a 120V 15amp source is enough to run the AC. Someone else needs to chime in.

Note the adapter will function well up to 15 amp. Any current above that will slowly damage the adapter; normally be overheating the connections and melting the housing.

You could put in a voltage monitor to show the supply voltage in the trailer. Something that just plugs into an outlet that you could directly read the voltage at that outlet. If the voltage becomes low with the AC on you would know things are not working correctly.

Are you just trying to plug the 30a cord into an outlet? You can buy an adapter at any number of places, including Walmart. My AC starts easily on a 15a outlet in my garage. I have nothing else on the circuit at the same time, though.

FCStreamer is right for one kind of adapter. They also make one that plugs into both sockets on a household (15 amp) receptacle so that you get more contact points, if not theoretically more power. Sorry I don't have a picture.

This is a good solution for me:

Furrion FP3015-SS Titanium 30 Amp Female to 15 Amp Male Pigtail

It is supposed to be "universal"; will connect to non-Furrion plugs.

It is available on Amazon for $52.26.

I have run my heat pump on the 15 amp garage circuit. I seemed to be fine with no voltage drop but I only tried it once.

Master electrician.

1)Make sure you have an extension cord made with #12 gauge wire.
2)keep the length of cord short to limit voltage drop.
3)don't run anything more than A/C and lights.
Should have no problems...stay cool

Geeze $52 bucks? You gotta be nuts. Try this:

$6.95 on Amazon and some Wal-Marts have them. It runs my A/C fine, but at my house it is on a 20 amp circuit, not a 15.

You cannot run the a/c with this adapter plugged into a 15 or 20 amp receptacle.
It will destroy the receptacle or trip the breaker.

I bought one that plugs in and can be screwed secure on the side of our AS for our 50AMP connection which converts to 30AMP and then another that converts to 15AMP. Bought them both on Ebay - $30.00 for both sold by individual. I've tested them and they work fine. They are available on Amazon for as listed previously $50.00 something a piece.

The CAmco adapter in the Amazon link is similar to what is found at WalMart and PPL.
They are referred to as "15A to 30A" adapters, because the shape/design of those "prongs" are what are normally utilized on circuits of those amperage ratings.
However, as one poster above has already mentioned, the so-called "15A" receptacle may actually be a 20A circuit, properly served by appropriately-sized/gauged wire, and with the receptacle being more heavy-duty than some cheapo-units. (Also, keep in mind that some 120 volt receptacles are rated at 20-25 Amps and have a "hot" side shaped with a horizontal-slot in addition to the vertical-slot. The Camco adapter will readily fit that type receptacle.)
Here's what it looks like:
The point I'm attempting to make is that 14 ga or 12 ga wire serving a 120 volt outlet is adequate for 15 amps but more than that would best be served by a 10 ga wire, and if you use such a higher-quality outlet, the Camco type adapter will likely work just fine for running the AC alone from your 30A supply cord.
The fears that some express are likely not an issue because if indeed the outlet is only rated at 15 Amps (or other) then the circuit breaker serving that outlet will trip prior to "melting" or any such thing. (Just don't attempt to keep resetting the breaker if it trips. Use a different outlet after you reset the breaker once.)

Master Electrician.

I hate to be one of those guys that split hairs but:
120 volt receptacles are rated 15 or 20 amps. If it will accept a plug with one vertical prong and one horizontal prong; it is rated for 20 amps. Otherwise figure on 15 amps. I have seen, literally thousands of times, 15 amp receptacles connected to 20 amp breakers, making the receptacle the weak link.
The National Electric Code requires (minimum) 14 gauge conductor for 15 amps, 12 gauge for 20 amps, 10 gauge for 30 amps. However, length of circuit, or voltage drop, is the most common culprit when having problems. So, bigger is better when it comes to wire size. In any case, when your unit has been up and running for a while, hold your power/extension cord and see if it is overly warm. If you 'think' it might be are probably Okay. If it is definitely warm or hot, you need to take action. Heat is the 'tell' that you have a problem.
