Power plug and outlet for PowerGenius XL?

Andy - KU7T

Getting ready for the XL, that may show up here in a few weeks. I already ran the wire in the wall to an electrical box in the shack (normal 110 twin outlet but not connected up).

I got an electrician lined up to help me with the 220V because I need breakers re-arranged and final hookup. I do not expect him to know what type of plug I need/should use. Can anyone recommend what plug is good for 220V ham radio equipment such as the XL?

Thanks

Hi Andy,

The plug doesn't really matter because Flex will give you a cord set with an unterminated end. You can put the plug of your choice on it. You can have your sparky wire either a NEMA 6-20R straight blade receptacle or a L6-20R twist lock receptacle. Those are the two common ones. Have them wire a 240v 20 amp circuit, which will use a double pole breaker.

Thanks for the prompt reply. Got it ordered... 73, Andy

I would go with the L6-20R Twist lock one, so that it is different then the rest of the outlets in the shack and household. That way noone will mistakenly plug a 110v device. I would try to find a red colored one and label it.

The NEMA 6-20R that Ria referred to is physically different than a 120 volt outlet. A standard 120 plug WILL NOT fit in a receptacle designed for 220 volts.

Salvador, 

In the U.S. typically red outlets indicate that the power source has emergency backup power. I would just go with the NEMA 6-20R or L6-20R. I did not use twist lock here as the outlet is behind the desk and there is almost no chance for the power cord to be pulled out accidently.

This is a 6-20. 6 series are 240v.



This is a 5-20. 5-20 are 120v.



The blade is horizontal vs vertical. Mirror images for the 20 amp. Zero chance of mistakenly plugging the wrong one in, unless you bend the pins.

Twist lock is fine too.

I have 2 240v recepts behind the desk, 6-20r

(For the many on this group who are already very aware of the subject of electrical wiring and safety this is not directed to you.)

David is correct, don't use RED unless the source has automatic backup such as generator.  Although at my qth I do have whole house generator backup but all of my outlets 120 and 220 are normal color (white) no point in doing so.

Look at the 5th and six rows of the following pdf chart under (2-Pole 3-Wire Grounding) Straight Blade Devices 125V 250V that applies here.

In no way can you accidentally plug in the wrong plug.  That is by design in the NEMA code.

ALWAYS use the correct outlet for your installation, this is a life safety issue NEVER stray from the code.
ALWAYS install the correct wire gauge, also a life safety issue, keep the burden of safety onto your breaker NOT your wiring.
My personal suggestion for your ham shack is to run conduit to the "shack" with THHN wire keeping yur equipment off of your house wiring.  In my opinion that is also a life safety issue.

I didn't know about the back up feature of the red colored outlets. Always learning something on this site.

The red basically is so in hospitals they can identify which equipment is powered by backup power so that critical equipment is plugged in there rather than in outlets that would suffer a power failure. I would imagine since Dave manages public safety comms infrastructure that he knows a bit about keeping stuff powered on.

That is what I do Ria, electrician / electronics tech in a hospital 30 years now.
A subject dear to  my heart.  Now safety coach is the latest feather in my hat.

I spent a month in the NICU with my little ones. I am grateful that so much attention is paid to detail!
