Improper connection of generator to a building’s electrical system can allow electrical current from the generator to backfeed into utility lines. This may result in electrocution of utility workers, fire or explosion. Connections to a building’s electrical system must be made by a qualified electrician and comply with all applicable laws and electrical codes.
Der unsachgemäße Anschluss eines Generators an das Stromnetz eines Gebäudes kann eine Rückführung des elektrischen Stroms vom Generator in die Stromleitungen verursachen. Dies kann u. U. zu tödlichem Stromschlag bei EVU-Mitarbeitern, Brand oder Explosion führen. Anschlüsse an das Gebäudestromnetz müssen von einem Elektriker vorgenommen werden und es müssen dabei alle einschlägigen Gesetze und elektrischen Vorschriften eingehalten werden.
La conexión inadecuada del generador al sistema eléctrico de un edificio puede hacer que la corriente eléctrica del generador se retroalimente en las líneas de servicios públicos. Esto puede provocar la electrocución de los trabajadores de servicios públicos, incendios o explosiones. Las conexiones al sistema eléctrico de un edificio deben ser realizadas por un electricista calificado, y cumplir con todas las leyes y todos los códigos de electricidad aplicables.
Le raccordement inadéquat de la génératrice au système électrique d’un immeuble peut permettre au courant électrique produit par la génératrice de refouler dans le réseau public. Les ouvriers de la compagnie d’électricité pourraient subir une électrocution, et un feu ou une explosion pourraient survenir. Le raccordement au système électrique d’un immeuble doit être confié à un électricien compétent et respecter l’ensemble des lois et codes en vigueur en matière d’électricité.
