Is it permissible for electrical contracting companies to work on electrical installations and protection systems in hotels in Egypt?

Working in the aforementioned field is permissible in principle. However, if the hotels engage in forbidden activities such as dancing, serving alcoholic beverages, and prostitution, then it is not permissible to assist with electrical installations or similar tasks, due to the help provided in sin. Allah Almighty says: "And do not cooperate in sin and aggression."
