Electrical Supplies To Lifts

Am asking if there are any specific requirements for an electrical supply to a lift installation.

At this point I have no details/specifications as to the size or rating but am trying to gain an idea as to what is actuallly needed up to the interface where BS7671 ceases and the lift regualtions take over, so basically the supply-only.

Can anyone with experience of this kind of intallation give me an idea as toi what the general size of supply needs to be in terms of current/type of OPD, backup requirements, and whether or not this supply can be connected to an existing dist board, or whether the supply has to be wholly independent of all others?

Comments welcome.

There are 4 staircases leaving the main hall for that purpose and are wholly adequate, so I don't foresee any need for any safety/building evacuation measures to include the use of a electric lift.

If you take people with restricted mobility up in a lift, you have to bring them back down again.

As BS 81-76:2025 points out, at one time, lifts were not to be used in the event of a fire, but policy has changed.

That said, what happens after the isolator is not your problem, so by all means quote for the provision of a new supply and leave it at that.

Just check that the main stair cases are the actual fire exits.

Often those main staircases can be open fancy glass based 'atrium' accesses.

My former work had that. The fire marshal’s main job during fire drills was to stop folks using the main glass doors and stair well because they were just 'pretty' and weren't fire rated! [The marshals had other equally important task as well ]

Looks like it applies to residential buildings rather than public ones.
