incorrect.  the old drier plug has a ground and 2 hot leads.  Although it is an irrelevant argument because the neutral is bonded to ground at the meter, at the transformer on the pole and most of the time inside the panel. Although the function of them is different,  In most cases the only difference between the ground and the neutral is the color.

I could make you an adapter pigtail.

Scroll down to the pic of the NEMA plugins and what they are for.  It still looks like a replacement dryer plug and a Nema 6-30R socket is an option.

to quote the web page " Not for use on GFCI or LDCI outlets. "

Neutral WAS ground way back when,I've got a friend who needed their dryer replaced,they got a great brand new dryer & OPPS they had a 4 prong on it...............

We ran a new 4 wire as it was real close to the breaker box,but still had no ground in the box.So we got a 8 ft ground rod & drove it in the ground & hooked the ground to it  

Not quite.  The NEMA 10-30 outlet has two 110V lives and one neutral.  The NEMA 6-30 wants two lives and a ground.  Your your picture of the 10-30 incorrectly claims the neutral is a ground.

I've been using a 10/2 cable from a dryer outlet like op's to a L6-30 for my pdu for almost a year. The thing to realize is that dryer outlet is 20+ years old so it is probably corroded, it may need to be replaced or cleaned if possible. You don't need a 4 wire setup for this just 2 conductors and a ground

lol who gives a shit, its there problem when you moveout =)

Yeah but doesn't the NEMA 10-30 dryer plug have two 110V lives and one ground/earth.  So changing to a NEMA L6-30P the only real hard bit is making sure that you wire up the ground/earth receptacle correctly.  While the other two 110V leaves don't really matter which receptacle that they're wired to.

Obviously just our Island then HellDiverUK 

Alternative!!  Get an electrician to make a box with the correct plug at one end and the ' correct ' socket at the other.  The full metal can type boxes can be mounted to a board or left on their own and usually have a ' strain relief ' going in.

With the weird things I can get my hands on, it would have been a 5 min cable making session that would include the box being grounded and tested to be safe in case of cats.
Dryer replacement cables are around 5 bux, the box is around 3 and the strain relief is another buck, having a cable ready after the move to take over the laundry room to mine coins... priceless!!

 

Incorrect.

Likely case is they make you pay for their licensed electrician to come in and put it back at whatever rate the local union charges.  Even worse is the house burns down and the fire marshal sees your "mod" and declares it your fault causing the landlords insurance company to back out and point at you.  But, enough fear mongering

What you have is a nema 10-30 plug.  Commonly known as an "old dryer plug".  There is no easy way of safely converting it to a nema 6-30 unless someone ran four wires to the box and only hooked up 3.  But looking at the vintage of that plug I would consider that unlikely.  That outlet has two lives and a neutral.  There is no ground.  Don't get me going on how someone could come up with a design that has a 110/220 volt appliance in a laundry room that is not grounded ... that's another story.

The "correct" thing would be to upgrade that plug to a "new dryer plug" which is a nema 14-30.  That will give you both lives for 220 along with neutral for 120 and ground.  You can safely piglead convert that to a nema 6-30.  Your landlord can not stop you from performing that upgrade by a licensed electrician in most states.  He may even split the cost.

Disclaimer: I am not a licensed electrician and this post does not constitute advice.  But please, verify what you have been told since much of what precedes my post is not only wrong, but dangerous.  A piglead conversion from a nema 10-30 to a 6-30 would be ungrounded.

I thought George would be a better name.

I think that you should call it Stuart.

When renting, do then ask for permission after (especially if its an upgrade). Worst case they'll force you to put it back, which again takes no time or money.

Np. I have a spare of each that I can ship you for the cost of shipping, so you can see if they would work.

Cool thanks a lot

Does a PDU offer surge protection if not what should we use.  I think we're going to skip a UPS as can't really afford it.  Can anyone recommend a good cheap 220V@30A PDU with NEMA L6-30P and two C19/C20 socket connectors.

Just replace the socket at the wall. No PDU is gonna be fitted for a washer/dryer outlet.
