The diagram in figure shows a three-pin socket marked as 1, 2 and 3.

(a) Identify and write live (L), neutral (N) and earth (E) against the correct number.

(b) To which part of the appliance is the terminal 1 connected?

(c) To which wire joined to 2 or 3, is the fuse connected?

(a) The points are labelled as follows:

• 1 → E
• 2 → N
• 3 → L

(b) Terminal 1 is connected to the metal body of the appliance.

(c) The fuse is connected to the live wire (numbered 3 in the diagram). It is so because if in case there is excessive flow of current, the fuse melts first and breaks down the circuit to protect appliances.
