The busbar is a low, straight line between the mains and the roof of a building, the purpose of the busbar is to provide protection to a motor vehicle from damage (e.g. electrocution) caused by touching the mains. Busbars also protect motor vehicles from damage due to falling objects hitting the roof of a building.<br><br><br>When looking at a busbar rating you need to take into consideration what is being rated for. The most common type of busbar structure is the grand busbar and distribution. The legrand busbar rating is used on buildings which are one level, straight, have a roof that has no openings (e.g. windows) and are symmetrical with each other.<br><br><br>The legrand busbar structure provides very good protection, it is an economical choice and offers a high degree of resistance to damage. It is often used in buildings that need a strong support for the roof of the building as it provides excellent weathering resistance. STS or Standard Terminal Shock Specification busbars are used where the protection offered is required in a building that meets the above criteria.<br><br><br>In STS ratings there is a requirement for a square shape of the busbar itself. This can be achieved by using a minimum of a 45 degree angle between the front edge of the pole and the front of the busbar structure itself. The STS busbar rating standard for this type of structure is 4.5amps/inches. As the squareness increases the resistance also increases, the higher the squareness the greater the resistance.<br><br><br>Another type of busbar structure is the symmetrical steel busbar. This has low resistance levels and high levels of stress resistance. The maximum squareness is again around 45 degrees and therefore the maximum structural design flexibility is possible.<br><br><br>An STS (statute) busbar rating standard is used when STS bars are used on a staircase, threshold or access ladder to prevent tripping on a flat surface. Any stair tread should have at least one tooth marked so that it will be easily seen if a person slips. The minimum tread depth is four inches. It is important to know that stair treads can be made from either steel or timber. Only products that meet the standard JISB (Joint Insulation Systems Standards) can be used to meet this requirement.<br><br><br>Timber-based solutions can offer a lower level of structural rigidity, but the timber needs to be treated for moisture resistance. An untreated timber busbar structure will need to be treated chemically after installation in order to make it safe to work on. It may also be necessary to install a protective cover after it has been installed.<br><br><br>If a stair lift user encounters a structure that does not conform to the requirements of the UK's busbar rating standard then they are able to take their case to the European Commission. The Commission sees that each member state should have busbars which meet the required specifications. Any non-compliance could subject a member state to fines and penalties. For more information relating to the requirements of your particular country, visit Stairlift Association.<br><br><br>Achieving the best performance from a stair lift, it is essential to ensure that the design and implementation meet the required standards. Failure to comply with the UK's safety standards could lead to fines or even immediate removal of the product from sale. You may have seen products that claim to comply with the UK's BIS Standard but are actually non-compliant. As well as naming the names of the individual parts of the BIS Standard, non-compliant products often provide a graphic representation of how the parts of the standard fit together. This enables users to assess whether the system they are using will be suitable for their requirements. Achieving the best possible result from any system is dependent upon getting the best design and implementation.<br><br><br>There are a number of stair lift manufacturers that currently market systems that do not meet the current standards. Many of these companies produce systems that are not designed for residential use and may therefore not be appropriate for the elderly or disabled. Many of the companies that currently supply stair lifts with low level access are also relatively new.

For these reasons, when buying a stair lift you should always opt for a reputable company who has a proven track record. Such companies may be able to offer custom tailored solutions that incorporate a range of different elements to ensure that your property is well supported.<br><br><br>If you live in an older property, you may already be aware that many home stair lifts are not compliant with the current British Safety Standards (BSS). In order to provide you with the most suitable stair lift system, it is recommended that you search for a company that has experience in both residential and commercial stair lift installations. In addition to ensuring a high quality product, this type of installation can also ensure that your property remains compliant with current legislation. It is vital that all stair lifts sold comply with the current regulations, and if you do not feel that your property meets these guidelines it is strongly recommended that you purchase a non-compliant stair lift.<br> '
