An electric service upgrade normally involves the complete replacement of electrical service around the house. This includes the line side service entrance cable, meter base, weather head, load side service entrance cable, the grounding and bonding system, and, of course, the electric panel itself.
Electric panels typically need replacing every 25-40 years. Even if the panel has not reached this age yet, there may be warning signs that it needs replacement. These signs include: Flickering lights.
