Where is the best place (on-line, I assume) to purchase 250 volt plugs
to connect to the bare end of a suitable extension cord/wire? I just
paid $10 at home depot for one, and I thought it was quite a
rip-off!!!

Thx,

Hello Michael,

It depends the number of poles, what voltage, ampere, type of material the
plug and connector is made out that may be plated brass, is it watertight,
can run a vehicle over it without damage, have straight in box lug
connections and a strain relief grip that even a 20 amp size connector will
accept a 1 inch diameter No. 6 AWG multi strand power cord.

I buy my cord sets from a whole sale electrical supply house for my EV that
is a inline plug and connector which is a nylon water tight 4 wire 4 pole 30
amp twistlock type made by Daniel Woodhead, that cost me back in 2000 about
$56.00 for the set. They had to order it, because it was not aa standard
stock item.

I just got done breaking this plug down, and remove contacts for cleaning
and polishing. Should be good for another 10 years.

I now tend to buy a lot of electrical items from Home Depot, (so do a lot of
other electrical contractors), because they may handle a larger volume of
some items which I can get it for the same or even cheaper then the
electrical supply house.

There are different time factors for many types of plugs and receptacles.
Even if it listed as a 20 amp plug, it may be only design to pull 1.5 amp
continuous, which is normal use for a residential in bedrooms and living
rooms.

For kitchens we may have to use a 3 to 5 amp continuous rating and in shops
we may have to use a heavy duty set, that a 20 amp receptacle and plug set
can take 16 amps continuous. These types of the industrial grade or hospital
grade type, that will accept eight No. 10 stranded copper wire in a heavy
duty box lugs which have feed thru leads.

These industrial grade which is needed for a circuit that pulls 15 amps and
must withstand a 5 lb pull out of the plug and may cost up to $20.00 at a
whole sale electrical house.

That's actually not too bad. These are not exactly mass-market items. I'm
a bit surprised that HD and Lowe's even sell them. I guess maybe they're
used enough on big power tools, compressors, and such that there's at least
some demand. But they'll never sell in the same quantities as 125v 15a
connectors.

BTW, a good quality Hubbell connector will probably cost even more than
that. It will also probably last the life of your EV (and then some).

You may be "spoiled" by the cheap (often imported) mass-market extension
cords with molded connectors. These are worth about what you pay for them.
A good use for them is to cut the ends off and use the wire to make your own
good EV power cables. Flexible cable gotten this way is often quite a bit
cheaper per foot than what you'd pay in similar quantities at the hardware
store. Check the voltage rating and make sure they're UL approved first,
however.

LOL, you think $10 is a rip-off? You do realize that if you order one
online you'll spend $10 on shipping alone?
