Knockout hole sizes

[OkiePC]

Looking at a part today online and the descriptions says:
"This enclosure has knockout hole size �D1 M20/M25 and PG16/PG21 available"

What is hole size D1?

TIA

Try Z-Tech; Panel Punches.com. They have a selection of panel punches. They list a "1D round with flat" among 23 D-style punches.

Unfortunately no idea! But know the others well enough to avoid the PG variants (Especially as I work with certified equipment!)

Dang I figgered fer sure one-a-you across the pond would know right off the bat.

Guess I feel less ignorant posting this question now...It's okay though, cause I gotta uni-bit and can make the holes bigger if I end up using that device.

Well M20 is about 3/4 and M25 is inch but I'm sure you knew that. The UK has used these metric sizes for donkeys years!

I believe PG gland sizes are less popular but we still have a Dutch production line that has SEW Eurodrive motors/gearboxes that have tapped PG gland entries.

D1 isn't any standard that I can find, but the M and PG are. I wonder if it is a reference to something in their own literature. That was the most common thing that showed up for it in a Google search.

Which manufacturer are you using? One manual i have for enclosures states the following 'D1' in its legend;

D1 = 5 x M20 as per Drilling Detail Table

It's for a disconnect switch from A/B with a composite housing. I don't think I will end up using them anyhow. Cat no. 194E-Y16-1753-4N.

Just a guess, maybe D1 is shorthand for Decimal 1, meaning one inch.

I had a look at the AB Catalog Page for the above, and the only D1 I can find is the Drawing reference to the Table below that maps to the M and PG Knockouts available for the Disconnect.

I found the diagram for the enclosure you mentioned.
This is a diagram key to be used with reference to the table of sizes below.
D1 refers to the knockouts on the top and bottom.
D2 refers to the knockouts on the sides.

Thanks guys. I didn't realize D1 was a drawing reference when I saw it here:

After following your links I see I should have gone here to find the associated chart:
