RTU Wiring
You have purchased a rooftop unit for your commercial facility to circulate air, heat and air condition the building. The installation is going as planned, but you need a commercial electrician to wire the components together for operation.
At Integrity Electricians, we can take this complicated system for building environmental control and bring it to life. Your rooftop unit runs a variety of functions that depend on electricity for operations.
The operation of the RTU is sequential in that it operates when temperatures get too cold or too warm, commanded by a thermostat to maintain a constant temperature. The thermostat is connected to the RTU system and tells it when to run based on preset temperatures or for air circulation.

Depending on the size of your rooftop unit, it will dictate what components, cabling, and wiring will be required to carry the current to operate the different functions that the unit will perform. When you chose us for the wiring installation for your unit, you can depend on Integrity Electricians to have the expertise and experience to complete the project.
The hardware for environmental control is installed by an HVAC company that seats the unit on the roof, and then we attach the different components to the main power supply. The system runs on a three-phase that uses a 420V AC power supply.
RTUs run a series of components like a compressor, blower motor, and condenser. Three-phase electricity is connected to a control panel with cables that are attached to a motor starter for smooth operation.
Suffice to say an RTU is a complicated system that depends on system interaction to create the programmed desired result. The work of wiring up the system requires the services of a highly-qualified commercial electrician to institute the steps required to get all the components to operate in unison.
At Integrity Electricians, we want to help you unlock the benefits of a RTU. When you are planning an upgrade to your facility, contact us at Integrity Electricians for a consultation of your needs.
We will take you through a step-by-step process to show you how we will wire your rooftop unit to meet the specifications set out by the manufacturer and all provincial regulations required to be fulfilled when installing your new equipment.
