I have a 4 "prong" dryer plug in my basement. Is there a converter
that will plug into it and let me plug in one or two 120VAC 30A
plugs? If there isn't such a converter, how hard would it be to
make one up? Thanks.
There's NO 60A line there. You have 2 30A lines which cannot be
connected together (this would produce a short circuit, actually
making 0A available). To get 120V you use ONE how wire and neutral. It
would be possible to connect two 30A appliances, but not a 60A one.
I have seen where someone was using a 240V receptacle for holiday
It was an older house, so probably 3-wire. That was supposedly unsafe
(current through a bare wire?) but probably not VERY unsafe.
Most certainly is, L5-30's. Data centers use them and the majority of RV's
use them as well. I have one on the outside wall of my garage for my camper.
Option 5, 4th outlet down at this link.
No such animal exists. If you need a 120V outlet, jury-rigging one from a
240V plug is not the right way to do it.
Why not replace the breaker and and plug thereby converting the line to
You could also just add new 120V line(s). You mentioned that this is
located in a basement. Don't know your specific situation, but it should
not be too tough to add a new line and outlet in a basement.
You could make an extended quad-receptacle box. 2 circuits at
120volts, each hot as feed and split neutral and ground to each.
It should be changed at the breaker...but would work. Jury rigged,
cobbled...Smoky Stovert style.
It will function fine in normal use. But the wiring and the outlets in
your 120 V strips are likely designed to carry 15 A, while they are
"protected" by a breaker that will carry 40 A. This isn't safe in an
overload, unless you change the breaker to a two-pole 15 A one.
