Electrical control panel design, fabrication & installation
A panel that is engineered right from the start keeps your machines running safely and is easy to maintain. Our engineers design, build and install control panels around each factory's production process.
E.S. Service and Supply has designed and installed electrical panels for industrial plants for more than 20 years, from small motor control panels to large main distribution boards. Every project starts with a site survey and a real load calculation, so breakers, busbars and protection devices are sized correctly: no over-spending, and no compromise on safety.
Every panel is assembled in our own workshop in Saraburi by experienced technicians, designed and checked by a licensed professional electrical engineer. Each panel is function-tested before it is delivered.
Enclosure size and heat management affect service life as much as the components inside. Every device in a panel gives off heat continuously; if the enclosure is undersized or poorly ventilated, internal temperature rises until devices misbehave or age prematurely. We therefore consider internal heat load, site conditions and the required dust and water protection (IP) rating from the design stage.
Wiring discipline and labelling are just as easily overlooked. A panel with tidy wiring, wire numbers that match the drawings and proper documentation lets your own technicians find faults quickly — and the production time saved is usually worth far more than any difference in panel price.

Electrical & Control Panels
Engineered by licensed engineers
Load calculations, single-line diagrams and panel layouts prepared by a licensed power engineer.
Components sized for the real duty
Load calculations drive the rating of every breaker, busbar and protective device, based on how your plant actually runs.
Built in our own workshop
Full control over assembly quality, wiring and cable labelling at every step.
Tested before every delivery
Wiring checks, insulation checks and sequence-of-operation tests before installation.
Leading-brand components
Our own warehouse stock means faster sourcing of breakers, contactors and controls.
Installation & after-sales support
On-site installation and commissioning, plus advice whenever you expand or upgrade.
Signs it is time to upgrade or replace a control panel
The panel runs hot or smells burnt
Usually loose terminations, aged cable or loads beyond the rating. A thermal camera survey finds these before they escalate.
Breakers trip for no obvious reason
Often incorrect device ratings, unbalanced load distribution, or components reaching end of life.
No space left for new machinery
Once a panel is full, forcing in more devices traps heat and makes maintenance harder.
Components are obsolete
When spares are no longer available, a single failure can stop production far longer than it should.
Wiring is unlabelled or does not match the drawings
Fault finding takes far longer, especially when the technician who knew the panel has moved on.
The enclosure does not suit the environment
Panels in dusty, humid or outdoor locations need an appropriate IP protection rating.
What helps us quote accurately
- Type and number of loads or motors, with ratings (kW) and voltage
- Existing drawings or a single line diagram, if you have them
- Installation area, available space and the route for moving the panel in
- Site conditions: dust, humidity, temperature, indoors or outdoors
- Component brands already used at your plant, or brands you prefer
- Required completion date and when production can be stopped
- Photos of the existing panel and the installation area

Real work from real sites
Frequently asked questions
Which areas do you serve?
Our office and workshop are in Chaloem Phra Kiat, Saraburi. We serve industrial plants across Thailand. Contact us to discuss your location.
What information do you need for a quotation?
A single-line diagram, a list of machines or loads, and site photos help us quote quickly and accurately. If you don't have drawings yet, our engineers can survey the site and design the system for you.
Who designs and checks the panels?
A licensed professional power engineer calculates the loads, selects device ratings and approves the panel drawings before assembly begins; every panel is then function-tested before delivery. If your project requires a specific standard to be referenced, tell us at quotation stage.
Do you modify or upgrade existing panels?
Yes. We add circuits, replace worn components and upgrade existing panels for new machinery, after an engineer has inspected the panel and the existing system.
What IP rating should our panel have?
It depends where the panel is installed. A panel in a clean electrical room needs less protection than one in a dusty area, a humid process area or outdoors. Our engineer will recommend a suitable rating once we have seen the actual conditions.
How long does a panel take to build?
It depends on size, circuit complexity and component lead times. Tell us your required completion date with your quotation request so our team can confirm what is realistic.
Do you support the panel after installation?
We advise on and modify panels we have built and installed, including adding circuits or replacing components later. Contact us with the panel details and the problem you are seeing.
Planning an electrical or control panel project?
Send us your drawings or project details. Our engineers will review them and come back with recommendations and a quotation.
