Testing that goes beyond the button
Pressing the test button tells you the mechanism moves. A trip-time test tells you how quickly it disconnects under a fault condition — which is what actually matters in an emergency.
We test portable RCDs and carry out mains testing and trip-time checks, recording the results so you have evidence the protection on your site is working.
Who needs it
Building sites, workshops, trades and any workplace using portable RCDs with power tools and extension leads. RCD testing is commonly booked alongside a full test and tag visit, so everything is done in one trip.
