• electricity distribution equipment that is a finished product, such as fuse boxes, consumer units and circuit breakers
• energy management systems – including sensors and displays
• loadbanks (testing systems for electric power supplies)
• PV inverters – small to medium installations, including micro-inverters (you must report as B2C if they can be used for households or commercially
• smart meters – report electricity meters as B2B and ‘add on’ meters or monitors for householders to manage their energy consumption as B2C
• thermostats and time switches
• traffic lights – temporary and mobile systems are EEE products (when put on the market as a single product) – for installed fixed systems (where parts are placed on the market separately) only the lighting and control equipment are EEE products, not the steel posts
