P. S. And ONLY an electrician should do this, and make the determination. However, it might be quite cheap compared to running a new wire. The key piece is that the circuit has to have nothing else on it. Sent from my iPhone using Inside EVs
Here is the thread where this first came up: https://www.insideevsforum.com/community/index.php?threads/are-there-level-1-evses-that-are-faster-than-the-oem-one.4258/page-2#post-43604 There is a lot of other stuff in the thread so it is a little cluttered. It is a very simple and elegant solution yielding a great result (when applicable). You can get to 4 hour charge time without the [sometimes great] expense of pulling new wires.
I get it now. The existing white neutral becomes one leg of the two 120’s needed for 240V. So, you would have the two “hots”, one white and one black, and ground, with no neutral. It would work, but the color-coding might not meet code. Also, if the outlet has a slot for neutral, not having a neutral might also be a code issue. Remember, I got my 240v from a hangar door installation with just two 120V hots and a ground, and it works.
Yep... It is standard practice to apply black tape to the white wire when it is used like this to signify that it is hot. A NEMA 6-20R 220V receptacle will match this configuration perfectly (it only has 3 contacts, 2 hot and a ground). As such, I [a non-electrician] declare that this is code compliant !
So are you charging using 110-120 volts or 220-240, because the plug you show is a 220 volt 20 amp plug?
@bpratt - you are right... I think @4sallypat accidentally showed a NEMA 6-20R which is indeed 240V (not 120). Pretty sure he intended to show a NEMA 5-20R (120V 20A). Here is a diagram of the various outlets:
Thanks everyone. This gave me a lot of information that is very useful. I just wanted to know if the add was co2in saying that the advertised charger really needs a 20 Amp to work properly. I have a 220 30amp in my garage that I use for over night charging but at my job I only have a 110 that have a 20 Amp outlet on it but I'm convinced that the circuit is actually a dedicated 20 Amp circuit , that's really why I was asking. Also the advertised charger is claiming that it charges 2x fasterbin a 110 than the supplied Honda charger. So I was asking for anyone that may have any personal experience with this.... Thanks again everyone.
That additional information is both helpful and important and greatly simplifies the answer, if you are still asking. As many have noted already, the advertised EVSE will NOT allow the car charger to charge 2 times faster than the Honda OEM EVSE on a 110 outlet. It can only take advantage of the incremental increase in available power going from a 15A circuit to a 20A circuit if the voltage on both is 110.
In other words, the stock charger is 12A at 110V. The new charger (to be used on a 20A circuit) is 16A. The 16A charger will charge in 75% of the time that it would take the 12A charger.
The knowledge base and helpfulness on the Clarity part of the forum never ceases to amaze me, save me money, and make me feel like there is still hope for mankind.
