Circuit breaker trips or fuse blows?

This problem is noticed when appliance voltage is not handled by the electric supply of the place.The voltage issues causes this types of problems and needs to be inspected.
Well if you have Blown a Fuse/Tripped Circuit Breaker, FIRST, TURN OFF THE MAIN POWER SWITCH. Now, If a Breaker, simply flip the lever, the "Other Way" or, press the button, on the Breaker Body to "Reset" it. If a Fuse, you will have to withdraw the Fuse(s) from the "Holder(s)" until you find the Blown one, look to see if the Fuse Wire is intact, or, not.. a Blown Fuse will have the wire broken/melted. You then, effect repair, by simply using a length of the correctly rated, Fuse Wire. (Replacement Fuse Wire will be of different thicknesses, for different Current Ratings, usually, 5 Amps, 10 Amps, 15 Amps, & 20 Amps). Simply wrap one end of the Fuse Wire, around the contact, at one end, or if screw connection, then under there, & wrap clockwise, then, .make it go through the little hole/slot in middle, and then, wrap it around the screw, or wrap around the other end contact Then replace Fuse, turn the Power back on. Always do all this with nothing plugged into the power socket too. Now if the Fuse.Breaker "Blows" or "Trips" again, with nothing connected, you have a Wiring fault. Also make sure the Unit that caused the problem in the first place is repaired, or it, simply do it all again.
Electricity problems must be inspected by proper repair techs.Basic inspection is definitely advisable, but major repairing must be inspected/checked by proper techs.
Thanks.

Power Outages?

Go through this details when you face power surge or power outage at your place.

We have all had them, Power Outages, inconvenient, and also very deadly, well to Electronic equipment anyway. You see when any Circuit, is Made or Broken, at the instant of contact, when reconnecting, the current draw is considerable, also, after the connection has been made, and the "Load" being connected, and the Current draw is large, all sorts of transients, Spikes, Surges, Oscillations, is reflected, up and down the entire network. Now along with this, MOST people do NOT completely remove, the unit from the mains, by withdrawing the plug. nor, probably, even turn it off. This is wrong, ALL/ANY electronic equipment, that is connected to that Grid, will also encounter a phenomenon know as "Inrush Current" Now, this Inrush Current, Can and Does cause a great deal of damage to electronic equipment, the, instant reconnection, without going through an ON/OFF switch, and Power Conditioning Circuitry, well, the initial Current draw for that instant, is incredibly, high, and with nothing between, the current surges in, stressing everything, in the Power Supply, and more. Now along with that, you also have Transients, Spikes, Surges, Ringing, Oscillations, caused by the reconnecting of the Circuits. Joining of Cables, or Contacts. When the Power Goes OFF, you should NEVER leave anything plugged in after a Power outage, you need to withdraw each and every plug, from ALL Electronic equipment, note here, purely resistive, and relay type equipment is usually immune, it must be removed, and it shouldn't be reconnected, until about 5 minutes, AFTER the Power has been reconnected. This is to Avoid, all of the bad things that are caused by the reconnection back onto the Grid. If you do this, you can be assured of you Electronic items, lasting at least as long as they should, and not suffer premature deaths.
This above mentioned details will help.
Thanks.
