Draper RCD Safety adaptor RCD3
Price: £12.95 Trip speed: 18.7ms
Although clearly related to the Focus and Homebase twins, this adaptor's design is different, and it's more compact. It has green and blue buttons on the front and, again, a very small hole for viewing its operational state - far from ideal when you're looking across a workshop. The test speed was average, but with a hefty price tag of £12.95, it is also the most expensive.
