Is your Garage as safe as your Tesla ?

Is your Garage as safe as your Tesla ?

How we use our plug in connectors in our garage needs a bit of attention!
Because many of you do not understand the importance of a good mechanical connection when charging your Tesla. A good tight mechanical connection is necessary for a good electrical connection. Sagging or sloppy connectors are a fire risk!

I use a HPWC daily not a problem. All of you lauding your savings at using your portable cord kit for daily wall charging may be seeing why it is better to use fewer plug together parts. Adaptors equal potential loose connections ! Daily usage of push together parts raises the risk of heat related problems!

In most cases plug in appliances a not installed and uninstalled daily. This is what causes heat related issues. The female connector looses its grip after repeated use and things get hot with loose parts.

I am a Hardware man we sell wiring devices . Plug fires are common occurrences . Be sure you have tight fitting parts that don't run hot. Arching equals fires eventually! Be safe don't use over heated or heat compromised parts. Does your cord run very warm ? You are the one who is responsible to keep an eye on this issue in your garage. Be safe !

Thanks for the reminder!

I've always viewed the UMC and related adapters as a way to charge when on the road or staying somewhere temporarily. I purchased the HPWC because I wanted the solution at my home to be robust and reliable. I am probably in the minority, as most likely went the NEMA 14-50 route.

AmpedRealtor, I'm with you. Plus there's the fast charging. It seems wrong to spend more time charging than driving. With an HWPC I can add range at 60 mph. Faster than it took to drive those 60 miles when you take average speed into account.

Minority or not the HPWC is vastly better than the cord kit for daily use. You got it right Amped...!

HPWC here too, but the public needs to be aware of the dangers involved with high amperage plugs/outlets, loose connections, faulty/missing ground & improper installs.

The adapter/cable will feel warm to the touch at high amps after a few hours, this is normal. But if it feels HOT! or you must remove your hand after a few seconds because of the heat, PLEASE have your install & feed inspected by a licensed electrician. Don't try to save a dollar here... your garage, car, home & family deserve better!

Another issues is the quality of wall devices used. Some 120v wall devices do not measure up . The quality 20 amp type have multiple contact points and really hold the male post very tight. High quality nylon faced devices work best. Some of the 79 cent devices are trouble waiting to happen! No loose connections Tesla owners!

Just a head's sure to check/know the duty cycle/rating of your wall outlet, especially a NEMA 14-50 or the like. They are not rated for many thousands of cycles, and the spring tension can fade after a while. FWIW, I have 2 NEMA 14-50 adapters. I leave 1 in the receptacle in my garage, and 1 in the black tote bag for the UMC. If I hit the road, I disconnect at the connection between the UMC and the adapter, and leave the adapter in the wall. Essentially NO duty cycles on the receptacle (...yes, duty cycles on the UMC connector, but TM can replace this if it fails without a call to an electrician).

Great Info... Thanks all above...

Yes, frequent (daily?) connect-disconnect with hi-amp devices is not a common experience, and needs special attention. Life & death issue!
