What happens if you mix up live and neutral wires?
What happens when Live touches neutral? The live wire touches the neutral wire. – This will create a short circuit as a large current which exceeds the fuse rating will from the live (240 V) to the neutral wire (0V) as that path has very low resistance. The fuse will blow.
Can you put a 3 pin plug in a round plug?
Exactly. Put a 3 pin plug on with appropriate fuse and it will either work or blow the fuse. To save cutting wires, I’d just get the adapter (round to normal 3pin) and put a 13A fuse in that. Jobsagudden. (Shame about all the misinformation available on forums these days really.)
Where does the white wire go on a plug?
Next, attach the white wire to one of the silver screws on the left side of the plug. And lastly, the black wire goes on the right side of the plug. (the brass screws). An easy way to remember which wire goes where is Black wire to Brass screw… Black and Brass start with the letter “B”. I know, it seems extremely simple.
What’s the voltage of a blue Plug and socket?
If it runs at 14amps say, thing will get a bit warm with a normal plug and socket. Have a look at the back of the power amp, it will have the voltage & current rating printed on the back. Or look up the spec on the manufactures website. Erm, not all blue sockets are 16amp, I have a 30amp one in my garage.
What’s the best way to wire a plug?
The first this to do is attach the bare wire to the back of the electrical box (wrap around one of the screws) but leave enough of a “tail” to attach the the green or blackish screw at the bottom of the plug. This ensures that the plug and the box are now grounded.
Where are the wires in the tug plug?
Hi all, just went to change my socket on tug from 7 to 12 pin and found it has two more wires in the plug. They don’t connect to any of the seven pins, they are the 2 very outside wires (purple and grey) light gauge and connect into terminals but I can only see a rubber type strip below the 7 pins in line with these terminals.
Is the 12 pin plug the original 7 pin plug?
Burnsy is that the original plug in your pic. If your changing that to a 12 pin plug make sure you get the one that has the normally closed reed switch. Hi seanparky, yes it is the original 7 pin plug. I bought a Narva 12 pin but doesn’t have the other terminals, is this for reversing sensor? please explain reed switch!
How does a trailer plug connect to a light gauge?
They don’t connect to any of the seven pins, they are the 2 very outside wires (purple and grey) light gauge and connect into terminals but I can only see a rubber type strip below the 7 pins in line with these terminals. Does anyone know about this and what they do?
Is there a 7 pin socket on a Pajero?
The 7 pin socket is a Lumen brand! Cheers. There is no voltage to these wires when car running or not. This plug was wired from dealer! Does your Pajero have reversing sensors and do they turn off when you connect the caravan. If so these could be the wires that disconnect the reversing sensors so that you do not pick up the caravan when reversing.
