Wiring and installation
The first step in the wiring and installation process is to decide on the type of temporary electric board you require. This includes determining the number of switches, sockets, and other components needed. Once you have a clear understanding of your requirements, you can prepare a wooden frame to fit all the necessary components.
After assembling the wooden frame, the next step is to install a transformer or an SMPS (switch-mode power supply) to enable the auto-cut functionality. This will help protect your appliances in case of an over-voltage situation. The transformer or SMPS should be comfortably installed within the wooden frame.
Now, you can begin the wiring process by properly distinguishing between the line and neutral wires. It is important to follow the wiring diagram or instructions provided with your components to ensure a correct and safe installation. Remember to select the appropriate relay ampere according to your load.
For a temporary power setup, you will need to obtain a temporary power permit and work with a licensed electrician to ensure compliance with local codes and regulations. The electrician will install the temporary power pole, panel, and any necessary wiring. Once the installation is complete, the local building inspector will approve the setup, after which you can contact your local power company to establish the temporary power connection.
It is important to note that temporary power may not provide sufficient electricity to run heaters, which are necessary to accelerate the drying process during construction. As a result, some builders opt for rented propane or kerosene heaters, but these can cause cracks in the sheetrock and create additional challenges during the finishing process.
