If you think you have an unsafe electrical installation (inverter) you should first warn everyone to stay away from it and – if safe to do so – switch it off. You should then contact a competent person, such as an approved contractor of the equipment from the supply company/ authority.
If the installation you think is unsafe is not owned by you or under your control, you should try to find out who owns it and then contact them. Electrical distribution poles, pylons and equipment (inverter) should have a contact telephone number attached to them.
If you can’t find out who owns or controls an electrical installation that you think is unsafe, you should contact your local authority.
