Our Voltimum Experts answer your questions on a daily basis in our Technical Expertise area. This Question of the Day concerns a lobby in a house of three flats and emergency lighting. It is answered by SELECT:
If each flat does need an emergency light fitting, is it the landlord's supply feeding it, or is it the tenant's supply?
Think about this, if landlord's supply trips on the landing, the tenant may not be affected, so his/her lights would remain on anyway. If tenant's supply went down, he/she would rely on this emergency light to get out of the flat. Generally, though, emergency lights are fed from landlord's supply. There is a three-phase supply in the house.
Answer: The lobby area of individual flats such as you describe would generally not require emergency lighting. Common areas along the escape route may require emergency lighting.
It may also be appropriate to contact your local authority to see if they have any specific requirements.
