Tips on neat cabling & avoiding terminal (wire) overload?
« on: February 18, 2017, 02:24:19 PM »
Hi,

Thinking about all the wires that might need to go into Aux+ etc and the keybus, what do people do to keep things neat and not overload the terminals on the panel?

I found these "Terminal Expanders' onlind (https://amazon.com/Box-TE126-Terminal-Expander-1/dp/B018NPVZOI) which allow you to connect two wires to the panel, but then have 6 others wires to share it each one benefiting from having dedicated a terminal.

Sadly they seem to be US only, hence I'm curious what others might be using?

Wire nut with a pigtail.

Interesting, Thanks

I was not familiar with that term, so I had to look it up ;)

Hopefully I found the right reference  - because that helps, as it makes me think of these things - which are called Wago

Here is an example of what I am referring to.  No special parts needed though they do make "official wire nut pigtails".  Simply wire nut the leads together with an extra wire jumper which is secured to the terminal.

Just be sure you calculate your load.

Thanks @AlarmMike

It's amazing that 'wire nuts' are surpringly uncommon/unknown here in the U.K. :) Thanks to your link and I found this too - http://waterheatertimer.org/How-to-select-right-wire-nut.html

Seeing as the principle for what that does is very common, bring wires together and create a tail/wire to connect to the board.

Wagos (http://toolguyd.com/wago-wall-nuts-pushwire-connectors/) are readily available here, and by the look of things they support the 22 AWG (solid) I have.

When it comes to 'calculating the load' what method do you use for that ?
Are we just thinking about the Aux+ and the 500ma panel limit ?

Depends on what you're wanting to bundle.  If it's powered sensors, then calculate the current draw from each sensor (i.e. motions, glassbreaks, smokes, etc.) so it doesn't overload the AUX output.  If it is modules such as keypads, expanders, etc. you need to calculate each one and ensure it doesn't overload the keybus.

You can grab a terminal strip too, either online for a few bucks from China shipped anywhere, or from what I read you might be able to source them at a local electrical shop (they are sometimes used for wire splices over there apparently)...

Or order a cheap box a wire nuts, or if you are looking for more permanent solution you can grab a bag of dolphin connectors if you aren't doing too many wires.

 B Connectors - White Dry non- filled, Beanie Alarm Telephone Wire Crimp Splice Clip - UPG Brand
Wire B-Connectors (a.k.a. "beanies") are made to exacting, original material specifications, to provide a strong, corrosion-free connection for years. Poorly made b-wire connectors can corrode or loosen their grip over time, adding significantly to circuit resistance. Spring-tempered phosphor-bronze teeth Nickel-plated for corrosion resistance Brass outer shell Suitable for 22-26 AWG wire Plain(dry) or sealant (gel-filled) Sealant-filled available in and blue

If you want really neat cabling within an alarm box, try searching for slotted wire duct something like this: https://amazon.com/PANDUIT-G1X1-5LG6-WIRING-SLOTTED-25-4MM/dp/B011NDKDMC  You can route all of the loose wires in the duct and then snap on the cover; but it is still easily opened for troubleshooting.  The wire duct also will hide beanie connections. 
I also prefer the din rail mounted contact blocks with the screw terminals, not the push in spring connects.
