Ferrule crimps -Types, tips and where to use them - inc Wago 221 and Nest connection

Bootlace ferrules help electricians create better electrical connections. In this electrical tutorial, we take look at the different types of ferrule including uninsulated, single-conductor and twin /dual conductor.

We explore where they are used, looking at RCBO flying leads and making electrical connections PCB connectors in a Google Nest thermostat heatlink.

A bootlace ferrule turns a stranded conductor into a solid conductor.

We show how a Wago 221 terminal can accept twin conductors using a twin ferrule.

Comments always welcome.

Love ferrules - often makes the job so much easier. The longer ones even let you insert a stranded wire into a wago push-fit connector such as the 773 series.

Just discovered that your Wiha crimper is in fact a Klauke K30-series crimper.

Klauke for the win...

Great video, excellent top tips I will be looking at using ferrules 👍👍

I have used very thin uninulated ferrules and thin coloured heat shrink sleeves to successfully repair a damaged PC keyboard cable in a pull out drawer in a 19" rack.... I spliced them so that they didn't all combine to make a huge lump in the cable...I also sleeved the cable with heat shrink in the vulnerable areas to save from future damage...
Much slimmer repair than soldering...

I was rewiring an office arming up the new board and one of my clients employees accidentally kicked a box with over 1000 ferrules in all over the floor. 3 hours it took him to sort them all out.

Great video - just to add that the Nest has three live feeds (terminals L to 2 to 5) and so you would need to do a double to a double to a single but we got the idea.

Insulated boot lace ferrules (I know they are aglet's on boot laces) invented by Telemecanique I worked for them when they first came out. Keep a drill bit the correct size in your box for when some prat steps on the box. You can get double Ferrules in the insulated ones the shoulder is oval.

When is the crimping tool video coming? If you could let me know...

[andrecostin]

With push type terminal blocks you'll need to use ferrules.

I one time did solder end of wire for a hot water tank 2.7kw ended up with a over heating end so then crimped it.

[martincherry]

Never swear as much as I do when I have to install a nest

[mfx]

Soldering stranded instead of using a ferrule is a big NO the solder "flows" under screw pressure over time and the connection becomes loose.

Moin!

👍no.1 for you with first message from me. 😁

[danield]

I done my apprenticeship in the industrial and commercial sector, one of the first thing I was taught by my journeyman was where to use ferrules, I’ve been qualified for a year and I’ve since moved on and I still use them everyday!

[thattoolguy]

Great video guys, must admit i only use non insulated, only because the OCD in me says the colour coding is rubbish

[zedman]

Great tips. Obviously not all ferrules are made equally. Are we concerned about the cheaper ferrules that are floating around that a lot of people will be using will not have the same electrical properties such that of copper/tinned wire?

[sypher]

5:43 As the insulation on the ferrule prevents the wire going all the way in, can you use a non-insulated ferrule instead?

[ashokpatel]

Great video. Thank you. I keep the insulated ones and when I need the odd one that's uninsulated I just split the shoulder with small sharp cutters and the insulation comes off very easily.

That wira crimper is 130quid on the Amazon, is there is cheaper option please ?
