Electrical system with closed compartment for preventing access to an electrical conductor extending in the compartment and methods for allowing and preventing access to an electrical conductor

A method for allowing access at least one electrical conductor extending in a compartment delimitated by a housing and closed by a cover for preventing access to each electrical conductor, comprising:

• removing a removable element proximate to the housing;
• moving a mobile hook attached to one amongst the cover and the housing from:
• an engaged position in which the mobile hook is engaged with the other amongst the cover and the housing to prevent the cover from being separated from the housing, thereby preventing an opening of the compartment, to
• a disengaged position in which the mobile hook is disengaged from the other from the cover and the housing to allow the cover to be separated from the housing, thereby allowing an opening of the compartment;
• and
• separating the cover from the housing to open the compartment;
• wherein the removable element, when mounted proximate to the housing, is configured to cooperate with the mobile hook to prevent the cover from being separated from the housing, thereby preventing an opening of the compartment.
