When remodeling an old home, upgrading your electrical lines should be included in your top considerations. Your electrical needs now are greater than back then. The main thing that you need to upgrade is the amps in your power supply. Most residences now have at least 100 amps. Ask for a computation to ensure that you won’t experience overloading in the future. Another item is the voltage. Most circuits have 120 volts for typical outlets, but for big appliances, you would need 220 volts. Of course, rewiring and replacement of outlets and switches should also be part of the renovation project.
Before requesting an electrical upgrade, you should first consider the kinds of appliances that you will need for every area. In the kitchen, for example, you should consider unconventional add-ons like food processors, blenders and espresso makers. Plus there’s the standard refrigerator, electric range, and microwave.
For living rooms and entertainment area, you should plan out where you want to watch TV so that cable wires can be prepared. Are you going to have a home theater system? If yes, wirings for surround speakers will have to be readily embedded, so they are not exposed. If you want to have ceiling fans, it will need a switch that’s separate from the lighting.
For the bedrooms, ask yourself which ones need computer access and internet access. Although it doesn’t require much power supply, you will need more outlets and a phone line for it.
For your garage or workshop, you are most likely going to use power tools. You will need a subpanel for this, and the electrical load should also be taken into consideration.
You should also anticipate other appliances that you might purchase in the future. As a rule of thumb, it is best to provide spare circuits for such needs.
