Q&A

<p>In the UK, the statutory supply band for electricity is now 230V -10% to +10% (i.e. 207V to 253V), following European harmonisation in 1995.&nbsp; However, the average voltage supplied from the national grid is 242V, whereas the average European voltage is 220V.</p> <p>Most electrical equipment used in the UK is manufactured to European standards, designed for 220V and will operate effectively down to 200V. By forcing appliances to operate at a higher voltage in the UK leads to significantly higher energy consumption, increased heat losses and a reduced life span. “A 230V linear appliance used on a 240V supply will take 4.3% more current and will consume almost 9% more energy.”&nbsp; (Electricians Guide 16th Edition BS7671). It is estimated that 90% of sites in the UK are operating at too high a voltage and could therefore benefit from installing a <strong><span style="COLOR: rgb(129,177,33)! important">power</span><span style="COLOR: rgb(0,39,118)! important">Perfector</span></strong>.</p>
