Nema 14-30 splitter

Nema 14-30 splitter

Hello, I am trying to use a Nema 14-30 I have for my dryer, I bought the Tesla adapter for it, but I have read that constantly unplugging and plugging back on the dryer outlet could damage it. I was thinking about getting a Nema 14-30 splitter, so I can leave my dryer connected and just plug my Tesla when I need charging. I would not be using both at the same time of course. I was looking at this product

Parkworld 886603 NEMA 14-30 Splitter, Dryer 14-30P Male Plug to (2) 14-30R Female Receptacle, Dryer 4-Prong 30 AMP 14-30 Y Adapter Cord https://www.amazon.com/dp/B07CVSSYQL/ref=cm_sw_r_cp_api_i_.ZgqCbQWZBQYT

Do you think this would be ok as long as I only use one at a time? Is it really true that plugging and unplugging a nema 14-30 dryer outlet could damage it? Thank you

I think that is way overpriced . I'd look for something cheaper or just make my own.

wiboater4 Sure I will look for a cheaper one, but do you think it’s safe? I don’t know much about this stuff as you can probably tell :(

If you use it like you say you will I think it would be ok but probably not up to electrical code. But I'm not an electrician either.

I'd just like to add that I spent the $500 for the wall connector and installed it myself for a little under $200. I drive the car into the garage , get out reach for the connector that is nice and close to the charge port and plug in. Since it's something I do everytime I drive it does seem worth spending the money on it. If you can afford it that is the way to go . now they do have the other connector that plugs into a Nema 14 50 outlet also. Call around to a bunch of electricians and get free estimates if you decide to do what I did.

I would not use the splitter. It is most definitely not code. If there were a fire or issue with the electrical system and the fire department or insurance agent saw that hanging from the wall whether the cause or not it could be an issue.

I would plug and unplug. It would take a lot of cycles to wear out the receptacle and if it does you could replace it. Better safe than convenient. Do you happen to have gas available at the dryer?

howard Thank you for the advice. What do you think about using an extension cord to the dryer outlet? I don’t think I have gas near my dryer, why?

f_calero, here is a link to a home charging guide some of the forum members put together. Although not an ideal solution, there is listing for a preferable splitter than the one you listed on Amazon.

As wiboater4 suggested, there is no substitute, both convenience-wise and safety-wise, for a dedicated outlet on a dedicated circuit (its own circuit breaker).

What howard is suggesting is that if you have gas in the house you could put in a gas dryer and free up the outlet for the car.

From what I have learned about charging cars in the 3 years I've been on this forum is that the weakest link in the chain is the OUTLET. They make a commercial grade version of outlets that can withstand a certain amount of plugging and unplugging. For myself, I would swap in such a heavy duty outlet regardless of whether I was sharing the receptacle or not. Again, it is the weak link, and an older, residential grade outlet is a variable. (and I take my own medicine. I just bought an EV and the first thing I did was order a commercial grade outlet). The charging guide I linked to above has details.

Cheers

f_calero, They do make heavy duty extension cords for a Nema 14-30. If you are just trying to make the plug swap out easier use a short a one as possible. It would not be preferable over direct circuit connection but I can see the issue with swapping it out all the time.

I'm surprised no one suggested a dryer buddy. It's a splitter that only allows one item plugged into it work at a time.

Actually, someone did.

SteveWin1 | 18 January, 2019

Yeah, I use a dryer buddy. Works great and tells me how much electricity I'm using.

Hi f_calero, wondering what you ultimately did regarding your dryer/EV plug? Did you get the splitter and if so, how does it work for you?
