Task: Simple Wiring Connection Layout of your House a) Make a simple wiring connection layout of your own house like the image shown below. The layout will be according to your house and the equipment used in your house. Mention the total load and current drawn by each room/spaces and the recommended size of cables to be used beside the cable lines. The following image is just an example and it is not complete. You may use standard symbols of the equipment or draw with appropriate label, i.e. fan, light, switchboard, MCB ete. b) Add images of equipment used in your house with this question.Most residential general lighting circuits are wired with 14-AWG copper conductors and are protected by 15-amp circuit breakers. However, there are many electricians who install 12-AWG copper conductors and protect them with 20-amp circuit breakers. How will you know which conductor size and which circuit breaker size will be used for the general lighting branch circuits in the house you are wiring?
