Joining conductors

[ekmdgrf]

Just wondering what the accepted method was for joining two conductors in alarm cable together?

I find bootlace crimp ferrules and a sleeve of heat shrink make a compact and reliable joint when crimped with a ratchet crimper.

Be careful with the heat gun as the insulation on some alarm cable melts even on the lowest heat setting of the hot air gun.

Junction box or solder together....

An alarm cable junction box with the appropriate level of tamper protection

Strip and twist together, including the insulation, and put into one side of a choc block.

I'm not a fan of covering everything with half a yard of insulating tape - it makes it difficult for the next guy to know what's lurking underneath.

I suppose as this is DiY that advise is ok then?

Alarm cable is quite thin, and therefore I would agree with Bernard Green and use bootlace ferrules and a crimp tool with heatshrink over. Chockbloc connectors are large and an eyesore, and can allow the cable to be disjointed very quickly! Owain DIYer's suggestion to use a tamperproof junction box is also perfectly valid, of course.

This is all that's inside some junction boxes and, as you say, this is a diy forum! Of course, graded systems require graded junction boxes but these won't be diy installs.

The best way is to organise your cable runs in your house that will not necessitate joints in cable, it's not rocket science or a huge factory.

Inside the control panel 2amp terminal strip will do the job.

LARGE. you're having a laugh.

ps I don't think many 20way JBs will be in use here (Terminal strip JBs)
