Adding a new power circuit
I have noticed as a result of using heaters this winter one of the power circuits in my house overloads and trips the 16A circuit breaker. At the moment the power circuit is for one bedroom, laundry and kitchen. I want the laundry on a separate power circuit. My house is a semi attached 2 storey terrace double brick house over 100 years old. I have been told to add the new circuit there are two options.
The first is to terminate the existing GPO in the laundry and rewire the existing GPO with new twin + earth wire 4mm. This new wire would have to travel a distance of approx 20m to reach the switchboard on the other side of the front door in a straight line in a 20mm conduit in the wall through a 300mm x 300mm trench.
The second option is to again terminate the existing GPO in the laundry. Then use the manhole upstairs to access the roof and drop down the new twin + earth wire down the cavity with one end in the laundry and the other end at the switchboard. With this way the both double bricks of the wall in the laundry would be removed to access the wires and rewire the existing GPO.
Could you please advise me which option i should take.
