content: I have a few tools in my shop that comes with very long and thick power connectors that are permanently attached to the unit and it is always awkward to wrap those back for storage as the cable tends to twist on itself since it is always tied on one side.As all power cables come with three internal conductors (Live, Neutral and Ground), I was wondering if there were any readily available 3 pin quick disconnects such as the ones we commonly see in the RC world (XT60,XT90 etc.) that were splash resistant and relatively compact.I'm thinking something with a metal latch for further securing but that is not a requirement.Does anyone know if such connectors exist and what they are called?

content: I don't have a part number but the Dewalt 618 router comes with a power cord and connector that meets your needs. I don't know if it is a standard part number. Festool uses a similar detachable cable though the connector is different. Post back if you find something, I have a couple of applications for it.

content: I saw a video the other day where a guy had used the 240V version of the "Speakon" connector for this (https://au.element14.com/neutrik/nac3mpa-1/socket-a-type-chassis-blue/dp/892373). They are compact and latching.As another option, consider using a system of individual "pigeon holes" for storing the power tools. That way, the cords don't get tangled together, and you can just throw them in there without coiling the cords up.

content: There's a whole bunch of these sort of things readily available from typical DIY stores.Or, y'know, they invented these things about 50 years ago:

content: Neutrik PowerCon true 1 TOP series is good. XLR sized, better water resistance than the original PowerCon True1 series. Now they can support load breaking which the original powercon's didn't. 16A 240V/20A 120V rating.Good all around, and individually aren't unreasonably priced, but if you're switching a bunch of tools over, and making up quite a few cable assemblies, it can get pricy.

content: Quote from: ConKbot on December 30, 2020, 06:55:52 amThat's a very nice connector but unfortunately it is still a bit on the larger size at 80 mm in length and it is not available locally just asked my Neutrik dealer.I have found something more compact and that suits my requirements perfectly. Looks well built too!https://www.aliexpress.com/item/4000240942297.html?spm=2114.12010612.8148356.7.5bc424b6s0HVgz

content: The powercons on Ali-Express are actuallylower in price then the M3 and are far safer for whatyou want to do. Plus they handle varying line cord diameters well.Steve

content: Quote from: LaserSteve on December 30, 2020, 03:39:03 pmTrue but I couldn't find them in black and I can't stand funky colors on such things as it will ruin the look of the tools it is attached to so for that reason, I will go for the M20 connector that I mentioned above.

content: One of the big advantages of the newer powercon1,apart from the load braking capacity,is the cable mount plug and socket couple together,unlike the original powercons that require an adapter box

content: Are you talking about stationary or portable power tools here?If you are talking about portable power tools seriously look at battery powered tools. Even with the overpriced battery packs you will save money versus keeping corded tools and you massively reduce frustration.If you are talking more stationary tools, you are always better off reducing connections to keep high reliability. When you absolutely need to be able to use optional power sources (outlets) look towards pin and socket connectors for high reliability. Usually there is a variant for every location on earth so you should have local approval for a pin and socket connector. These are industrial connectors for the most part so may be slightly expensive. Here is an example of one:https://www.alliedelec.com/product/lapp-group/720224fx/70124246/?utm_source=google&utm_medium=cpc&adpos=&scid=scplp70124246&sc_intid=70124246&gclid=EAIaIQobChMI8eDj6K727QIVZgeICR0udA_TEAYYBSABEgIckPD_BwE&gclsrc=aw.dsA second option is to simply install long cords on "stationary" equipment. Build in or onto the frame, a way to store that cord.By the way if you go with pin and socket connectors they are often vendor specific. On the other hand the old NEMA twist and lock units are standardized. However the pin and socket connectors for the most part are more reliable.Quote from: drummerdimitri on December 29, 2020, 04:29:05 pm
