Professional liability (E&O) for electricians

Coverage

What it covers for electrical contractors

Professional liability — errors and omissions — covers losses from errors in judgment, breaches of duty, or negligent acts in the performance of services for others. For an electrical contractor the exposure follows the design side of the trade: if you provide design, load calculations, or design-assist services — sizing a service, laying out circuits, advising on a design-build job — an error there is professional judgment failing rather than workmanship. It is a separate exposure from the jobsite bodily injury and property damage that general liability addresses, and a shop that only installs and repairs to someone else's plans carries little of it. An electrician who designs — service sizing, load calculations, design-assist on design-build work — is selling judgment as well as installation, and judgment errors are a professional exposure of their own.
