Why not just use the same box as the RV parks are using ?

http://www.pplmotorhomes.com/parts/rv-power-cords/multi-outlet-power-box.htm

They also make a stench cord with a plastic handle on it to help keep
your fingers away from the prongs.

Gentlemen (and Ladies)
I have said this before, there is available an alternative
"Charging
Station" substitute which it seems to me makes an excellent interface
between the circuit breaker in your service panel and an outlet to match
your cord to your EV and this is called a "Spa Disconnect and GFCI in a
rain-tight box for indoor or outdoor mounting. Just Google for it when
you
need it but after reading 20 of them I found this one at about half the
price but selling the same unit... the URL is *
http://www.spadepot.com/shop/Spa-GFCI-Load-Center-up-to-60A-P9279C193.aspx
*
use it with weatherproof covered outlets for the 240 vac and the 120 vac
mounted within 12 feet of this box and your city inspector will
_probably_
think it is OK . It will give a very professional appearing
installation. *(This
information for educational purposes only because I am not a licensed
electrician in your jurisdiction!)*

Electrocution at 120 volts isn't nearly as likely as at higher voltages, but
it's still a hazard of sorts - especially for infants, young children, the
sick, and the elderly. I don't have any way of judging how big a hazard
this is. I can't be sure, but I suspect that people are more likely to
injure themselves in jerking away from a shock than they are to be injured
by the shock itself. You might fall off a ladder, for example.

The US 120 volt 1-15 plug design is about 100 years old! If it or the 5-15
plug were invented today, the design would never make it to the market. The
developers would be afraid of liability.

As you say, it's way too easy for a careless user to contact live terminals
when connecting or disconnecting the plug. To make things worse, old
receptacles can become worn and fail to retain the plugs, so that plugs
"droop" from the wall receptacle under the weight of the appliance's power
cord. I've seen this happen in my own old houses. (These worn out
receptacles can also lead to fires because they don't make good solid
contact.) The cure is replacement of the receptacles, of course - especially
in a household with children. But this isn't always done, especially in low-
income situations.

I agree 100%. Such a design could easily be made backward-compatible. It
isn't unprecedented, as plugs have already been somewhat upgraded in recent
years. For example, it's no longer OK to sell the simple replacement plugs
we all used 30-40 years ago - remember the rubber and plastic ones with
nothing more than a fiber disc covering the terminal screws?

This is another place where EVs could lead the way.

Larger RVs are wired for 240 volt / 50 amp service using the 14-50
receptacle and plug, and have for many years, but I've never heard of
anyone being electrocuted using it. One thing they do is have a
breaker next to the plug. You make sure the breaker is turned off,
plug in your RV, and turn the breaker on. Thus, the circuit is not
energized when plugging in and unplugging. There's no interlock, just
everyone with an RV knows to do this. A plug with a handle on it so
you wouldn't have to grab the plug would be a simple addition to
increase safety.

Here's an example of possible adaptations to the US-Standard 3-prong
outlet:

One of the upgrades that I did in our house when we had kiddos is to
switch to a 3-prong outlet that requires that both blades be pushed in
at the same time to defeat an INTERNAL plastic lock, so you wouldn't
forget to replace the outlet cover (or the little one pulled the cord
out, or figured out the 'puzzle' of how to slide the cover over if using
a face-plate tamper resistant unit)

Looks like it made it into the code for new buildings:

Electrocution at 120 volts isn't nearly as likely as at higher voltages,
but
it's still a hazard of sorts - especially for infants, young children,
the
sick, and the elderly. I don't have any way of judging how big a hazard

this is. I can't be sure, but I suspect that people are more likely to
injure themselves in jerking away from a shock than they are to be
injured
by the shock itself. You might fall off a ladder, for example.

The US 120 volt 1-15 plug design is about 100 years old! If it or the
5-15
plug were invented today, the design would never make it to the market.
The
developers would be afraid of liability.

As you say, it's way too easy for a careless user to contact live
terminals
when connecting or disconnecting the plug. To make things worse, old
receptacles can become worn and fail to retain the plugs, so that plugs
"droop" from the wall receptacle under the weight of the appliance's
power
cord. I've seen this happen in my own old houses. (These worn out
receptacles can also lead to fires because they don't make good solid
contact.) The cure is replacement of the receptacles, of course -
especially
in a household with children. But this isn't always done, especially in
low-
income situations.

I agree 100%. Such a design could easily be made backward-compatible.
It
isn't unprecedented, as plugs have already been somewhat upgraded in
recent
years. For example, it's no longer OK to sell the simple replacement
plugs
we all used 30-40 years ago - remember the rubber and plastic ones with
nothing more than a fiber disc covering the terminal screws?

We've had shuttered outlets in the UK since 1947 :)
