According to the International Association of Certified Home Inspectors (InterNACHI), you should make regular checks to your electric panel, even if you haven’t needed to undertake any electrical fixes. In particular, you should check for signs of rust or scorching, both of which indicate underlying damage to the system.
Electrical panel maintenance, therefore, should be part of your regular routine. However, in some situations, it will be necessary for you to upgrade your electric panel to a more advanced system.
