But you can't clip on your voltmeter meter to the wires.
A pigtail with (insulated) alligator clips could be determined to be safer - if your standard practice is to clip onto the test leads before plugging into the receptacle. I like it better then trying to plug the test leads into the "hot" cord connector.

How about one of these?
It could also come in handy for current measurement of corded loads.
It has probe holes on the end.

It is actual test equipment so you will look more professional than using a cube tap.

- Provides easy and safe measurements of current without the need to cut off the plug and separate the conductors
- Plugging the power connector into the Line Splitter separates the hot/live conductor from the neutral (and ground)
- Also features voltage check function

But it does not give you equally convenient access to the ground pin.

You could use the 3 prong outlet in the end of the unit.
This has a male 3 prong plug on one end and a 3 prong female connector in the other.
Nothing is perfect for everyone.

The problem with any of these safe workarounds (especially the line splitter pictured) is that the newest generation of probes come with insulated tips which make it especially hard to insert them into any kind of device in North America and impossible to use with the test holes in line splitters.

Insulated tip---sounds kind of counterproductive in a situation where conductivity is important

I know, my bad
What I'm referring to is that the newest standards for test leads for electrical testing require a max 4mm exposed probe tip. Many testers are now sold with these. Some companies have a retractable design, but others include test leads with permanently insulated tips with only 4mm exposed. It's impossible to test a North American receptacle with these probes, tamper resistant or not.

Which means more people will be breaking out adapters of some sort that subject them to more exposure so that they can get a reading:roll:I know, my bad

What we need is a plug block with rotating prongs (so you can set it for 15A or 20A 120V or 240V) and three jacks to plug DMM leads into. In fact, I might make something like that It won't have the rotating prongs, but oh well.

I suppose I will need to just keep a cube tap or other adapter handy , I don't think there will be a large market for such a device.
