L14-30P, vs. L15-30P:

A chase nipple is a smooth throat threaded fitting with threads on one side and a flange of the size required to fit the hole.

Hey thanks Dave. I'll grab a few of those tomorrow as I need to get by the supply house anyways.

I didn't install that cord myself. It was like that when the saw was purchased. I installed the L15-30 plug to show as reference to ensure I was on the same page as skilled electricians. I'd surmised I was incorrect and appreciate the guidance.

Purchased a dozen each of L15-30P, and L15-30R from Amazon receiving on Friday afternoon. These are off brand but very high quality from OCS Parts. They came in quickly and I am quite pleased overall. I ordered on Jan 2nd, and received on Jan 6th so not bad. I've ordered from them in the past and been satisfied so pretty good people to deal with

Found a brand new package of T&B 1/2" cord grips on ebay for a really good price so got those acquired as they fit my 10/4AWG SO cord just fine:





Each machine will have a small "dongle" cord hanging from it with a male spade twist lock plug. This way I'll only carry a couple of extension cords with me to power any certain machine.

What is the differences between these two items? (L14 vs L15)

To answer the question of L14-30 vs L15-30, I have confirmed the difference. I have two different projects going, so I ordered both in both P(lug) and R(eceptacle)/C(onnector) varieties.

They look exactly the same but the purpose is different, so the wiring is different - one is for 240V single phase, the other is 240V 3 phase. The bent blade is Ground for both. For the remaining 3 blades, either 2 are hot or 3 are hot.

My orders were not arriving in the order that I could use for implementation, so I decided it didn't matter if I used L14 for L15 or vice version, since in my hand they all looked identical. Where I should have used L14, I wired up an L15 Connector (receptacle plug). When I tried an L14-30P, I found 3 blades fit but not the fourth. This is a good thing. It means that when implemented correctly I cannot plug a single phase device into a 3 phase outlet and fry my equipment or create a fire or health hazard.

Here is the detail on the L15 Pass & Seymour Connector that I used. You know how regular household outlets and plugs have one blade wider than the other? Same goes for L14 vs L15. One of the L14 hot blades is wider than L15. Maybe there is not as much danger trying the inverse of what I did - to plug 3 phase into single phase, because the device would only get 2 hots instead of the necessary 3 hots. But do not interchange their use, for at some point you will be tempted to grind the wider L14 blade so it fits into L15 and enable it to possibly plug into a true L15 3 phase.
