Electrical Supplies To Lifts

whjohnson

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.

  • Just like any other installtion covered by BS 7671 110.1.1 the installation needs to be designed in accordance with Regulation 132.1.

    I would suggest that the design is not a job for an ordinary electrician but a person who has a good knowledge of the requirements for lifts. The LV installtion normally stops at the lift controller. As has already been said if the lift is one used for a safety service such as a fire fighters lift, escape lift or special hospital lift then BS 7671 Chapter 56 will need to be complied with in addition to all the other general rules. There are other British Standards that will need to be complied with but top of the list in BS 8519.

    As Chris says the BS EN 81 standards for the lift wil need to be complied with depending on the intended use of the lift. The standard for evacuation lifts, BS EN 81-76 is only a draft IK believe at the moment so the lift designer will work to this if required. The completed lift installation will ned to be inspected by a lift inspector before being put in to service. 

    If this is a safety service lift the intended electrical design will need to be submitted to the Fire Engineer for the building in the form of a Technical Submittal for approval to ensure it complies with the fire strategy for the building.

    As I previously stated, I don't want anything to do with the actual lift installation, but merey to provide an adequate and correctly rated supply to the destination isolator. Whatever leaves the isolator is something for which I wish to have no responsibility for. Am guessing that the lift company will provide and be responsible for the complete package after the supply isiolator, including the actual lift,l ancillaries and all other compliance issues.

    At the moment there is no information to go on and this project has been rumbling on  for a few years now due to funding issues. As for escape routes etc, I see no reason to involve the use of a lift at all. 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.
