Little green dot on receptacles?

[hockeyoligist2]

I keep seeing a little green dot stuck on receptacles in Dr.s offices. I have saw these in some manufactured homes. What do the mean? Does it mean it's been checked? I have never bought one that came with a dot.

I've seen that too.

I didn't know the answer until I googled it and found this article on Receptacle Grades.

Actually it's just Hospital Grade, they can be purchased as tamper resistant.

Although you may see them in Doctors offices they are not required in these spaces, see 517.18 and 517.19 for where HG receptacles are required

Roger,

What characteristics make the receptacle hospital grade? I have limited experience in health care facilities and just accepted what I have learned in the field to be true.

Why are they in manufactured homes? I have also saw the green dots on smoke detectors in manufactured homes. Hospital grade smoke detectors?

Daniel, the short answer is that they are Extra Heavy Duty, I had a PDF that explained in detail the test criteria but, the link is not working right now, I'll try it again later.

For one thing, much greater plug-blade retention, and made to withstand more plugging and unplugging.

I don't know except that maybe the manufacture wants to use the best available receptacle.

The green dot on smoke alarms is not specifying Hospital Grade, I don't know what it means.

That green dot is meant to signify Heavy Duty+ extra requirements:

"Hospital Grade Receptacles
In addition to complying with the general use requirements, hospital grade receptacles are specially designed and are subject to additional requirements of the standards. These include additional grounding reliability, assembly integrity, strength and durability.

Hospital grade receptacles are offered in 15 A and 20 A straight blade of the ANSI/NEMA WD6 5-15, 6-15, 5-20 and 6-20 configurations. They are intended for use in accordance with the National Electrical Code, ANSI/NFPA 70, Article 517 (Health Care Facilities) in the United States and the Canadian Electrical Code, Part 1 CAN/C22.1.02, Section 24 (Patient Care Areas) in Canada.

Hospital grade receptacles have the same markings appearing on general use receptacles, but include additional markings denoting their intended use. These additional markings include the phrase "Hospital Grade" or "Hosp. Grade" appearing on the back of the receptacle (where visible during installation) and a green dot located on the face, visible after installation with a cover plate secured as intended.

UL does offer listing to a special locking-type receptacle rated 20 A, 125 V. The identification is very similar except it is marked "Hospital only" with no green dot appearing on the face."

I hope that answers your question.

I would really like to know how I do that! It would makes things so much easier when I start my counterfeiting operation.

Oh oh, I deleted 480's duplicate post before I read Chris's replies, sorry.

No.... I seriously don't know why it does that so often. I just click "Submit Reply" and I end up double-posting.

Occasionaly I will get a message to the effect that my post is similar to one posted recently, and won't let me submit it. Or I must wait another 59 seconds to submit my post due to the 60-second 'rule'.

Maybe I have an evil twin that's online somewhere else the can read my thoughts and is posting the exact same thing I am. Of course, I'm the real 480! :smile:
