Pls help??????????????????

Question

1)what are the basic aid procedures that should be followed in the event of someone having an electrical shock?

2)what is the danger of a cord connected to the mains having insulation which is worn through?

3)why should you not replace a broken fuse with a fuse marked at a higher current rating?

Answer 1

1) Do NOT touch them or you will probably get shocked as well.  Turn off the power to whatever is shocking that person -- circuit breaker, switch, etc.  If you can't turn the power off, then get a plastic or wooden stick, like a broom handle, or piece of wood 2x4, and push them away from the live wire.  After the power is cut off, or they are moved -- administer CPR if necessary, and treat for shock (as in medical shock, not electrical shock).

If they are being shocked by an overhead power line that has come down off the power-pole, all you can do is call 911.  Do not even get 20 feet from a downed live wire from a power pole.

2. Bare wires can come into contact with water on a kitchen counter and energize that wet spot and any other metal touching the wet spot (like a stainless steel sink).  It becomes much easier to get a shock that way.  OR... you could simply accidentally touch the bare wire and get a shock.

3. If a circuit is designed to blow a fuse (or circuit breaker) at 20 Amps and you replace it with a higher 30 or 40 Amp fuse, then if the circuit draws an overload of 25 Amps, the fuse will not 'blow' and the circuit might catch on fire.
