Retrofit
Retrofit refers to adding new technology, features, or components to older equipment or buildings to improve their performance, efficiency, or bring them up to current standards. In electrical work, this often means upgrading old lighting systems, electrical panels, or wiring to modern, energy-efficient alternatives. Think of it like giving an old car modern features - you're not replacing the whole car, just updating specific parts to make it work better. When you see this term in resumes or job descriptions, it usually means the person has experience modernizing existing electrical systems rather than installing completely new ones.
