LOAD STUDIES · INFRARED THERMOGRAPHY · ELECTRICAL INSPECTIONS
Find hot connections and failing breakers while the equipment runs, before they cause an outage or damage.
Infrared thermography uses a thermal camera to find hot spots in energized electrical equipment, such as loose connections, overloaded circuits and failing breakers, before they cause an outage or damage. A bad connection adds resistance, and resistance makes heat, so a thermal image shows trouble that looks normal to the eye.
Phoenix Contracting Services scans panels, switchgear, breakers, disconnects and service equipment at commercial and industrial facilities across the Phoenix area. We scan while the equipment is running under a normal load, because that is when problems show up.
Resistance makes heat, so a loose lug or termination shows up as a hot spot.
Conductors and breakers carrying too much current run warmer than their neighbors.
One phase carrying more than its share shows up as uneven heat across a panel.
A breaker running hotter than identical ones beside it deserves a closer look.
Heat at bus bars and lugs can signal a connection that is degrading.
Aging parts often run warm well before they fail.
Seeing warm breakers, flickering lights or trips with no clear cause? Call (602) 564-1144 and describe what you are seeing.
We list the panels, switchgear and service equipment to scan, check access and schedule the scan around your operations.
A qualified electrician exposes the connections where it is safe and scans the equipment while it is energized and carrying a normal load. Every hot spot gets a thermal image and a regular photo.
You get a written report with the findings and what to do about them. If corrective work is needed, we are licensed to do it.
Scan when the equipment is working hard. In Phoenix that is usually summer, when air conditioning pushes electrical loads to their yearly peak. A connection that looks fine in January can run hot in July, so a summer scan is often the most revealing. We can scan any time of year as long as the equipment is energized and carrying a normal load, and we schedule around your operations.
We scan panels, switchgear, breakers and service equipment from Square D, Siemens, Cutler Hammer, Eaton, Westinghouse, Crouse Hinds, Murray, Zinsco and Federal Pacific. Our work covers offices, warehouses, retail, data centers, manufacturing plants and multifamily buildings, plus larger residential projects. See our commercial electrical services and industrial electrical services.
[PLACEHOLDER PROJECT EXAMPLE: one real thermal scan. Facility type, what was scanned, what the camera found (equipment, temperature difference, likely cause), and what was done about it. Replace before publishing.]
NFPA 70B treats infrared thermography as part of electrical preventive maintenance, and a scan report documents the condition of your equipment for maintenance records. Some insurers also ask for that documentation, and carriers set their own requirements, so check what yours needs. We can scan once or help you set up a repeat schedule. See our NFPA 70B compliance services.
Yes. We are a licensed Arizona electrical contractor (ROC #153656), so if a scan finds a loose connection, a failing breaker or an overloaded panel, we can make the repair. See breaker replacement, electrical panel upgrades and service upgrades.
If the heat points to overload, a load study shows whether the system has enough capacity. See electrical load studies.
OUR PROCESS
Every job follows three steps: a site walkthrough, testing and documentation, then findings and next steps.
We visit the site, look at the panels and service, and agree on what needs to be tested or repaired before any work starts.
Load loggers and a thermal camera record what the equipment is doing, and the results are documented for each panel or component we check.
We go over what we found and your options in plain language. If corrective work is needed, we are licensed to do it.
