Install electric meter on dedicated 240v EVSE circuit ??

[truav8r]

I know I've seen folks on here who did this already, just looking for some guidance/advice. I'm planning to get the Siemens Versicharge bottom-fed plug-in model. I ran 6/2 wire (plus ground) from a 40A breaker, didn't install the 6-50 receptacle yet so this would be an ideal time to install an electric meter in-line before I finish the wiring. The typical household "bubble" electric meters are dirt cheap on eBay - about $25. Can I install one of those meters on the wiring I'm planning to use? It's 6/2 so we're talking 2 conductors and a ground. Is that compatible to have an inline meter like that??

Thanks for any help, sorry for being an electric dunce.

Should work great...Here's another source that people have used...

I saw that exact site when doings research. But when I look at their wiring diagrams, looks like they call for a neutral as well?? But I don't have a neutral, just my 2 conductors and ground.

I'm good at following directions, I just need those directions to be idiot-proof

The wiring is really simple for 240 Volts, as you can see from the wiring diagram:

The meter should work fine without a neutral.

Also, please note that most meter bases come with a neutral lug bonded to the case of the meter base. This is because the meter is typically installed before the service disconnect, where there is no ground established yet, so the neutral is used for bonding. However, after the service disconnect the ground is used for bonding cases and the like, and the neutral and ground should never be interconnected.

So the upshot is that for use after the service point, a lug bonded to the case of the meter base should only be used as a ground lug, not as a neutral lug. For an EVSE that works out great, as you don't have a neutral, and you can land your ground conductors on this bonded lug. In a different situation, should you have a neutral in your circuit, you will need to either pass it through the meter unbroken, or add a neutral lug that is insulated from the case.
