hlothery, enroll in the CPS flex plan so you can get $250 Rebate and extra $5 dollars a month along as you stay enrolled.

Sign up for FlexEV Smart Rewards and receive a $250 credit on your utility bill for allowing CPS Energy to make remote adjustments to your eligible level 2 WiFi charger*. Adjustments can occur between the hours of 2:00 p.m. and 9:00 p.m. Monday-Friday when the demand for energy is high. You’ll still have plenty of time for a full charge each night, and you’ll earn a $5 credit on your utility bill each month you remain enrolled in the program.

 

No thanks. Don't want CPS adjusting anything I'm trying to do. I won't give them access to my thermostat or my ChargePoint charger. No amount of money can entice me to allow them access to control my house. YMMV.

 

Please read this tread. We have no privacy with the EQS. Thank You All Members of EQS - MBWorld.org Forums. Follow the steps and you'll be the judge. I was never told that I was in a contract with ChargePoint thru Mercedes Me Connect.

 

Super informative thread guys. Thank you.

I have two 6/3 copper runs with 50 amp breakers and 14-50 outlets.

Down the road, if I were to want to hardwire connect a 50 amp charger (instead of plugging my 40 amp into the 14-50 outlet) I would change the breakers to 60 amp and be good to go, right?

second question re charge point vs juice box: any material differences as far as MercedesMe integration and/or charging on the road, away from my home ?

 

I bet the wire is too small for a 60 amp breaker. I have a charge point flex 50 amp plugged into a nema 14-50 outlet on a 50 amp breaker.

 

hey TH, my wiring is 6/3 NM-B, which i think is rated for 55a. Does the 80% rule apply to the wiring too? in my case, can it carry 50 or 48 amps continuous?

electrician says yes, provided we change breaker (currently 50a).

for now sitting tight with 14-50 plug in and 40a but wondering if down the road this wiring is sufficient for carry larger loads

 

My install is a 50amp circuit. Whether the plug is 6-50 or 14-50 doesnt matter they are both the same amps. All you are going to get is 40 amps through them. That is perfectly fine since the cars charger is 9.5 amps, ergo, you will max out the car's charger! To get 50 amps at the tap you need a 60 amp circuit. A major unnecessary expense given that the car will have no use for it! You can set the Charge Point for 40 or 30 during the installation. Always set it at 40.

like i said, wondering about down the road (other vehicles, for example). plan is to use as is for this vehicle at 40amps

 

Dont try to futureproof too much. 60 amp wiring is expensive and very difficult to install. Given the situation I don't see much use for it. Even vehicles with much bigger batteries than the EQS are going any bigger with AC chargers. Consider how many are willing or able to spend 12 to 15 hundred bucks to plug their car? Just on charging infrastructure (including chargers) for 2 homes Ive spent more than 2k!

 

i hear you. Can 6/3 nm-b carry 48 or 50 watts continuous ?

 

Let me ammend this Ford has an EV charger thar runs on 50 amps its 1000 dollars. It is recommende for the bigger powerpack in the lightning. I guess it has an 11kw charger.

 

sorry not sure if you’re trying to answer my question, but my question is: can 6/3 n-mb carry 48 or 50a continuous?

 

sorry I dont know. What is 6/3?

 

6/3 = 6 gauge wire with two hots and a neutral. My electrician used that with a 60 amp breaker to hardwire my Tesla Wall Connector. It gave me a 48 amp charge, the limit for my Model X. My EQS 450+ only needs a NEMA 14-50 but I used the same 6/3 and 60 amp when I disconnected the WC and installed a NEMA 14-50 plug. Probably not to code, but it is working fine so far.

 

Absolutely code. No worries. Im paranoid about electrical safety. I have checked the entire connection for temperature while charging, from the "charger" to the car the cables barely get warm. From the fuse box to the outlet the cable does not change temperature at all.

 

I was mistaken I did add a 60 amp cicuit not a 50. Again, overdone. I was expecting the EQS charger to be 11kw instead of 9.5

 

C400 and NCTalking head: did you guy see post above from DDruker earlier? What he said seems to be at odds with the approach of using 6/3 NM-B for 48 or 50a continuous charging. He is saying that the wire itself needs to adhere to the 80% rule for continuous charging. So according to that, 6/3 rated at 55a is not suitable for 48 or 50 (80% of 55 = 44).

My electrician thinks 6/3 N-MB is fine, though, and isn’t bound by that rule.

I don’t know, conflicting opinions out there. Just trying to come up with definitive answer

 

I think now that you’ve gone to the 14-50 outlet you want to put in a 50 amp breaker
