2008 NEC is the latest. The next revision isn't due until next year.


Thanks drees. My error's fixed.

So a plug-in EVSE is legal, so long as it's only used indoors? Well in most cases they will be indoors, in people's garages. That would be soooo much simpler not having to go through the hassles and expense of calling an electrician to permanently install the thing.

It would even be simpler if you only had to have an electrician install an L14-50R receptacle, connected to a 40A breaker, and then plug in the "charging cord", even that would be less costly than hardwiring, and you could take the adapter cord with you, when travelling, if you needed to.

BTW, this is the exact scenario in the UK and Japan... Of course it's not "good enough" for the US. BS I say.

No, clear as mud. Read it again:

One probably still needs a permit for installing a 240v socket, the wiring, and the breaker.

ALSO, the San Diego "EVSE Guide" mentions a "fused disconnect" in their parts list, in addition to the 40-amp breaker.

This might be a local San Diego requirement, a SDG&E requirement, or just a safety suggestion. Any knowledge here?

Well, I carefully read sections 18, 19, and I skimmed through 29. It appears to me the purpose of sections 18 and 19 are primarily to make allowances for a plug-in 240V EVSE.

The way I read it, there is no requirement for the EVSE to be hardwired, so long as it is equipped with "an interlock that de-energizes the electric vehicle connector and its cable whenever the electrical connector is uncoupled from the electric vehicle." (625.18) and an "automatic means to de-energize ... upon exposure to strain" (625.19). If the unit is 120V those requirements are expressly withdrawn, and if the unit is indoors then 625.29 details the applicable requirements.

In other words, a 240V EVSE can simply plug in and does not have to be hardwired so long as it's designed to de-energize itself when unplugged from the car or exposed to strain.

Well, if Nissan is trying to tell us that we cannot buy a LEAF without having an AV EVSE installed "by AV", then ...

perhaps we should inform Nissan that we will not buy a LEAF unless it comes with (or can buy) a portable, plug-in, reasonably-priced, 32-amp capable 240v EVSE.

But, we (on this forum) are WAY in the minority and many will buy the LEAF even if they have to have 2 meters installed and have "only one place" to do a 200+ volt charge.

I suppose the UK, EU, and Japan do not have this "problem".

If Nissan can engineer and make (or have made) a $17,000 Level 3 charger for the companies that want to over-charge us for charging, ... they should be able to provide something for us, their real customers.
