In commercial buildings, wired-in appliances like heaters, and boilers quietly drain energy, running when no one needs them. Traditional fused spurs can’t prevent this. But now, you can.
AI-powered fused spurs give you automated energy savings, real-time usage data, and remote management of these often-forgotten appliances, helping you reduce operational costs and carbon emissions.
The problem: Invisible power drain
The solution: Smart fused spurs for automated appliance control
Simple to install, easy to scale
"My electric radiators already have built-in timers"
“What about Legionella risk from turning off hot water tanks?”
“Can I cut power at the fused spur to an AC unit?”
Proven impact: Real results from real sites
How AI-powered fused spurs help you
A fused spur (or fused connection unit) is a wall-mounted outlet used to power a single, often high-energy, fixed appliance.
You’ll often find them tucked behind walls or cabinets, connected to:
They’re hard to monitor, and harder to control.
This creates a blind spot for facilities and sustainability teams trying to reduce building-wide energy consumption.
Traditional fused spurs are passive. Once something’s wired in, it often stays “on” indefinitely - sometimes 24/7. That leads to:
measurable.energy’s smart fused spurs automatically detect and eliminate energy waste. Using AI and real-time data, the system:
We know what you’re thinking: “This sounds great, but it probably means downtime, rewiring, and extra cost.”
Not with us.
Quick to install, easy to manage, and designed to deliver ROI fast.
“My electric radiators already have built-in timers.”
That’s a good start - but difficult to manage at scale. They get changed and devices switched to always-on without you knowing. And what if you have hundreds to manage? And exactly how much energy reduction are your timers enabling? It is impossible to know. Our fused spurs measure energy consumption 50 times a second and hence tell you exactly how much you are saving.
“What about Legionella risk from turning off hot water tanks?”
There is no risk of legionella from turning off hot water devices overnight and at weekends, however, consideration is needed for longer timeframes.
Our system can be configured to ensure essential appliances run according to health and safety guidance. You stay compliant, while still cutting unnecessary out-of-hours use.
“Can I cut power at the fused spur to an AC unit?”
Yes, it’s safe to cut power to an AC unit at the fused spur or plug socket. While startup does cause a brief surge in current, the energy, cost, and emissions savings from turning units off during extended downtime far outweigh any impact from restarting.
measurable.energy’s smart fused spurs are already helping organisations cut energy waste, lower emissions, and improve operational control. Here's what recent customer data shows:
Each smart fused spur saves an average of 2.1kWh per day with automated schedules active.
Average daily savings can be higher depending on the appliance type and usage patterns.
Switch off specific heaters, fans, or pumps automatically based on real usage patterns - no more blanket shutdowns.
Customers can reach ROI in just 81 days, depending on number of devices and usage patterns.
Track usage and emissions at the individual appliance level - data you’ve never had before.
Know exactly what’s using power, when, and why with automated control over every appliance.
Power trip alert? You’ll know instantly, no manual checks or downtime surprises.
If you’re managing energy, you’re under pressure to:
Smart fused spurs help you hit all of these without major retrofits or disruption.
