Child proof outlets
« on: April 23, 2017, 11:31:17 AM »

Child proof outlets now also adult proof.

I was doing some work in a church where they rebuilt the stage. They put some new electrical outlets on the edge of the new piece of stage. I went to test to see if it was wired properly with my NCVT and I couldn’t insert it into either the hot or neutral slots. I then realized it had the child protection built into the outlet. I wasn’t having any problem with the power I was just curious. I guess this is the new way of doing things. So I will now need to always carry a grounding plug adapter to be able to get the probe into the slots to test the power.

They are designed so both prongs have to be inserted simultaneously. Just stick both probes in at the same time, then pull out the one you need to poke elsewhere.

The NCVT (non-contact voltage tester) is a single probe device.

TR receptacles have been mandatory in residential since at least 2014.  The 2017 code significantly expands mandatory locations in most public places where children are likely to be.  The can be a pain from a testing standpoint, but they are an inexpensive way to provide some protection to children.

NCVT is a pain with TR.  A circuit tester should get the job done, be similarly small, and also tell you if it's wired properly (accepting that it can't sense bootleg ground).

And bootleg ground is what I wanted to test for.  :'(

FYI, Tamper Resistant outlets were required in the 2008 code book.

For voltage checking I modified a set of leads to my Fluke meter to have a 5-15 on the end.

Bootleg or reverse polarity?  The ground pin is not protected by the TR feature?

JR--the older I get the shorter years seem to be....I didn't realize it had been that long.  Inspectors have been "suggesting" TRs in commercial child friendly places for quite a while, I wasn't too surprised to see the additional requirements.  If you buy receptacles at the big box stores, you pay a quite a premium for the TR feature-not so much at the supply house, IME.

I agree that is what I was referring to in my first post when I said " So I will now need to always carry a grounding plug adapter to be able to get the probe into the slots to test the power. " I wonder how many names it is known by?  :)

 It's called 'cheater plug' but it's name is 'grounding adapter (plug)'.

I always thought "cheater plugs" were the lines cords used to bypass the safety interlock preventing powering up hot chassis TV sets with the rear metal grate removed. The standard line cord was attacked to the rear metal so the only way you could apply power was with the rear cover in place.
