'Bus bar' question

[RotorRouter]

A nieve question.

What device is used inside a homemade CNC case to distribute power from one wire to a number of motor controllers, etc?

Thanks.

wires

From what I can get from your question you have answered it your self, a buss bar, if the power needs to be selectable then a multi terminal rotary switch.

Note Rotary is not as in Rotor craft

Sorry. The question was poorly stated.

Second attempt.
Is there a stock (purchasable) item that is an alternative to using a terminal strip and jumpers?

Thanks again.

Ken, you're right. The name was intended to be 'RotorRooter'. :frown:

here is a high tech Answer: A bolt with an insulated washer to isolate it from the sheetmetal!

Or if you want more than one spot for attachement: a piece of metal that is isolated from the chasis with bolts for wire attachement!

or like both answers above.

buss bar with jumpers and of course Wires..

Let us know some specifics on what it is you are needing to accomplish, I cannot imagine anything simpler then a buss bar, there must be more to your question then appears.

Ken,

No, nothing complex.

It had been mentioned on this forum that devices should not be strung together in series.
I therefore bought a number of different terminal strips, only to find out that one type didn't accept jumpers, the distributor was out of jumpers for the other types, and nobody stocked bus bars.

It looks like I'll have to use my favorite tool, the sledgehammer, and forge a few bus bars. That is if the sledgehammer isn't used on the controller first.

Thanks again.

I usually use the terminal type that accept the miniature bus link, made by Weidmuller or Phoenix Contact, Weidmuller also sell small copper buss bars 2mmx5mm and up for some custom applications, you have to drill and tap for termination though. It looks like you already covered the options.

How funny! A few months ago I had been wondering where I could buy off-the-shelf bus bar, like you describe. Then a few days ago I bought a used enclosure which was stripped of all the old components, except for panduit and.... EXACTLY WHAT I HAD BEEN LOOKING FOR! WooHoo!

A quick search of ebay for "bus bar -greyhound" turned up quite a few options I wish I knew about some months ago. Isn't it funny how much difference knowing the correct name of somethign makes in today's search-engine driven world?

Go to Home Depot and check the electrical section for service boxes that are used to hold circuit breakers. Usually a line of products is sold along side to support customizing the service box. Also check local electrical contractors and their outlets. This is fairly common stuff.

If you are having a problem locating from local suppliers, then check the windmill/wind turbine sites up there in Canada. Many of the folks have figured out how to either make it themselves or found unusual supply outlets. These guys also need wire and bus-bars.

Good luck.

I get my copper busses (1/4" by 1/8") from the local metals supply yard. Last time it cost me $3 for 3' for the stuff.

Thanks for the ideas.
