Electrical installations at commercial buildings often include new power connections as well as upgrading of the existing power supply. Inside the buildings these installations will be power supply points i.e. plugs and lights. Often in these cases the lights will be part of displays at building entrances. It can also be a requirement for outside and walkway lights.
