Electrical codes require that the main circuit panel must be grounded, and the neutral at the main panel connected to this ground.
What happens if ground wire is not connected? ›
Grounding helps protect you and your home from the dangers of damaged circuits or electrical overloads. When power surges happen, the excess electricity introduced to the system could leap out of the wiring. Without electrical grounding, this stray voltage could start a fire, damage appliances, or shock bystanders.
