Thank you so much my good Sir, I've paid a lot of money for an electric course which I am currently doing, you've explained much better than my teacher you've simplified it and made it so much better for us to understand, you sir got your self a like and a subscriber..

[Frankyfish]

Incredibly clear and concise. Thank you for properly explaining earth requirements.

This helped me understand it all so well. Clearly spoken and perfectly described. Good job!

[CaptainDarling]

Great video! Thanks for your simple to understand explanation!

[AndrejsZavaruhins]

Thanks. Great sequential summary, both schematic and practical. Now I figured what letters L N E on the plug stand for and, therefore, can now solder the power cable.

[Ulandos]

Got confused at 8:42 . Is the casing Earthwire is connecting to the cooker itself or is it the cable?

[FishingReelsTV]

You are a fantastic artist and a brilliant teacher!

I currently got a light fitting with 2 wires one is white the other is black. With what wire do I wire them with?

[claystudiofx]

Nice video, i have a question : i'm not an electrical guy... How to make sure that the LIVE/NEUTRAL wire inside the wall outlet is installed properly (The L should be in the left side of the wall outlet) . If their position is switched, the fuse won't work right? Any advice ?

[alpachino]

Hi Roger, fantastic video, thanks! Can I just ask, if we have fuses in our plugs that protect appliances from high currents, why would we ever need surge protectors in extension leads?
