Electrical supply equipment is needed when using power tools or to connect various electrical appliances. These equipment need to be certified and should have the capacity to carry out the needed electrical load. Arwani offers ESMA certified cable reels and power bars from Stanley. The rugged Power Bars are useful for tough DIY and trade applications. Power bars & reels are classified by number of sockets and length of the cable. Cable reels have additional overload protection in case the product is over loaded with the power requirement more than its capacity.
