Uninsulated jumpers are no longer legal in Europe as they pose a shock threat due to lack of insulation. The WBT Power Bridges address this problem as they are fully insulated with Makrolon® plastic for shock protection and, because both terminals are removed at the same time, the “live-wire” situation is avoided. The back of the Power Bridge is damped with an elastomer to minimize vibration. Power Bridges can be used in conjunction with any WBT binding post (except the WBT-0702 series). When purchased with WBT posts, Power Bridges make an excellent modification to any bi-wire loudspeaker. Please refer to the diagram to the left for required mounting dimensions.
