Lysuttak

Lysuttak is a term used in Norwegian to describe the socket or outlet designed to connect electric lighting devices to a power supply. In practice it denotes the lampholder portion of a lighting fixture or a dedicated socket mounted in a building to accept a lamp. A lysuttak provides the conductive path between the live and neutral conductors and the lamp, and may include mechanical features to hold the lamp in place and, in some designs, an integrated switch or dimming control.

In residential use, lysuttak types correspond to lamp bases. Common mains lighting bases include Edison screw types E27 and E14, and bayonet bases such as B22d; for low-energy or specialty lighting, socket types like GU10, GU5.3, or G9 may be used. The choice depends on the fixture and lamp; the socket must be rated for the lamp’s voltage and current and provide safe insulation.

Standards and safety: Lysuttak installations fall under national electrical standards. In Norway this typically involves NEK 400 and related EN standards; work should be performed by a licensed electrician. Correct rating, proper wiring, grounding, and protection by circuit breakers are required to minimize the risk of electric shock or fire.

Maintenance: Periodic inspection for wear, overheating, or loose connections is advised. Damaged lampholders should be replaced with equivalent or higher-rated components.
