how you guys connect the wires together?
using those terminal blocks

Terminal block good for simple and low current usage equipments like light and fan. High current stuff I use solder and shrink tapes.

Hard to reach area caps are good. If high current use caps need to be careful may burn if not properly screw, loose connection will cause heat=burn=fire.

ok will try that. ya man if i use terminal blocks, i also scared the thin wire will break if screwed on too tight...sigh
btw developers where got put terminal blocks for you? they leave it bare. they cut the insulation a bit and twist together.

If Wires too thin, the block will not secure the wires properly. Fold back the wires into the wire insulator, so the top is copper, bottom is wire insulator, put it on the terminal block. This way you secure the wires, and copper are properly touching the conductor.

I wonder if I should not strip the insulation at all. Just tighten the screw till it cuts into the insulation. I always do that for three pin plugs  tongue.gif

Nope, contact will not be good.

This way the wire always break inside the insulator after tight the screw.  And there is possible the thin wire didn't touch the screw at all. Just the insulator is tight by the screw.

There is another way is to get a straight metal connector. Clamp the wire on it. Than screw it to terminal block.

Roll the wires together, and turn it back to touch the insulator. This will work better. if have soldering, just solder the copper and put inside the block.


BTW, lots of people don't know how to join wires when solder. This site show proper way http://www.ripsdiy.co.za/cablesandwires.shtml

Hi!
Need some advice smile.gif

I have 2 20A switches in my kitchen which are unused:

When I first renovated years ago, I couldn't decide if I wanted to get a microwave and oven fitted into my kitchen cabinet, so I left those cabinet empty, and my contractor just terminated the wires for me.

Top:

Questions that I have:
1. What is the difference between the top configurations and the bottom configurations?

2. I want to buy a microwave with oven combo: Something like this specs: Panasonic Microwave Oven
These microwave ovens normally come with a normal 3-pin plug. Can I remove the plug and connect the microwave wires directly to the 20A switch wires via the terminal connectors?

Thank you in advance for replying!

both the same, the one you see 2 green because the earth is loop to another location and you must have both the earth connected.

Not advisable, get a box, put in a socket, and use that sockect for your microware oven, the plug supply by microwave is for safety measurement, it have a 13amps fused.
