Hmmm, isn't the difference between pins just 0.1 °C ? Am I reading that data wrong ... ?
17.5 °C AC Power L1, delta T = 12.0 °C
17.4 °C AC Power L2, delta T = 11.9 °C
Yeah, now I'm confused. I thought Phil said it was only bad with a 15F or greater difference between the top two pins.
Mine was only a few degrees difference, but now I'm not sure if the crimps are good or not.

Ecotality / Blink has begun changing out the charging nozzle on owners who have a Rav4 in Phoenix.

Well. So the rest of us can have ours blow up when we upgrade cars in a couple of years? Are they just doing them all, or are they waiting for complaints?

So far, just the teeny tiny number of folks with a Blink and a Rav4 who are still in the EVproject (have a LEAF or Volt in the project).

I'm going to guess its a singular digit number of folks. Heck, they've only sold 270 Rav4's total.

I think my Blink is ok. I charged for almost 2 1/2 hours @ 6.0kW and the left pin was 125F, right was 130F.

Did you measure the current draw from the wall?

What was the ambient temperature? If ambient was 70 F, you have 55 or 60 degree F rise so I think both pins are marginal. By the way, what are you charging that will take 6 kW? Did you get a RAV4?

No, but it should be 32A?

No, should be 30a, since no known J1772 nozzle is rated by UL at 32 amps; 30, 40 and 75 amps, yes.... just not 32a.
