Main Distribution Board or Fuse Boards

Main Distribution Board or Fuse Boards ( Consumer Unit) usually contains three things.
They are:

  1. DP = Double Pole MCB  (The main switch)
  2. RCD (Also DP) Residual Current Devices.
  3. SP = Single Pole MCB ( Circuit Breakers and Fuses)

it is used to control and distribute electric supply (safely to electrical appliances) around your home  
1)
DP = Double Pole MCB  (The main switch)
This allows you to turn off and on the electric supply to your home because this is the main operating switch to control electric supply. remember that immediately switch off the main switch in emergency i.e. in electric shock, fire or  while working on main board. You can use also multiple mains switch if you has more supply unit i.e storage heater etc. so then use a separate Fuse board. 

2)  
RCD (Also DP) Residual Current Devices.
A (RCD) residual-current device, or (RCCB) residual-current circuit breaker , is an electrical wiring device or switch that disconnects or trip a circuit whenever it detects that the electric current is not balanced between the energized conductor and the return neutral conductor. And then instantly disconnect the electricity (in dangerous conditions). 

3)
Circuit Breakers  

Circuit breaker is a device which switch off and on electric supply at normal ( and abnormal) condition). These are automatic protection devices in the Main switch board or fuse-box that switch off a circuit if they detect a fault. the size of the fuse and Circuit Breaker are similar, but it give more and more protection. You can reset it again if the trip ever.

    assuming at 1000W/m2, a solar module power output is 100W at 25C and the average total radiation per day G= 4600Wh/m2. compute the number of modules required for this installation

  6. The professional electricians that completed the electrical installation in the entire residential complex in my locality are the <a rel="nofollow" href="http://www.electrician-johannesburg.com/east-rand/">the best in East Rand</a>, and I trust them for all sorts of electrical repairs.

  7. My local electrical service provider showed me the <a rel="nofollow" href="http://www.electrician-johannesburg.com/">groovy looking home page</a> of his website, and I was literally impressed with the quality of their work as well as the user-friendly website design they had created.

  8. why not copy

  9. The information in your article is incredible. Very good article. It is very well written. I am looking forward for your more posts in the future. <br /><br /><a href="http://www.epsgroupaustralia.com.au&quot; rel="nofollow">High Voltage Commissioning</a><br />

  10. You can connect the sub-circuit or final sub circuit to the out put of SP (Single Pole) Circuit breaker.. in other words, click on image and check the SP&#39;s breakers outputs (1-8)… you can see the mentioned title as &quot;Live Wires or Phase Supply to the Sub Circuits or Final Sub circuits&quot;.

  11. Can anybody advise me The wiring diagram of USB socket for house wiring.

  12. can you please tell me in this wiring diagram, should we connect earth bus bar with neutral bus bar? i have seen this connection often. is this configuration is correct?

  13. Hi there
    Am looking for wiring diagram for single phase without RCD CONNECTION FROM ENERGY METRE PLS PROVIDE ONE FOR ME
    THANK YOU

    Hi, I need to check with you guys if the edited image on the attached pic is possible to do.
    This is for the purpose of optimizing my home plug speed, since the Router is connected on a different circuit (Living Room) from my Bedroom circuit.
