Committed to Excellence
In this digital age, we’re more dependent on electronics and electricity than ever. DITEK Surge Protection is a proactive investment to safeguard your most valuable electronic and digital assets. It’s like insurance for your communications, fire protection, security systems, home appliances — anything you plug in to connect to power.
We all experience power surges every day. Those surges can damage your electronic and digital assets even when you can’t see them. DITEK Surge Protection guards your assets against big and small surges so your business or home can stay operational without fear of damage or downtime.
DITEK Surge Protection is the first line of defense for protecting power systems from the negative impacts of power surges. For over 35 years, we have been an industry leader in the technology, design and manufacturing of surge protection solutions for facilities, businesses, homes, and more.
SURGE PROTECTION BASICS
Surges and spikes are temporary and instantaneous events that increase normal electrical line voltage, and can cause serious damage to sensitive equipment. Conventional fuses and breakers do NOT guard against power surges and spikes.
What causes surges and spikes?
Lightning: A direct hit is usually catastrophic.
Proximity Strikes: Lightning strikes several miles away, causing large voltage spikes along transmission lines.
Brownouts/Blackouts: Under-voltage or sag, that is immediately followed by an unusually high voltage transient. If your lights flicker or dim, it’s usually an indication that a brownout occurred.
Utility Grid Switching: Utility companies switching transmission lines from one supply system to another.
Inductive Loads: The switching on and off of electric motors inside or outside a facility. For example, HVAC systems or heavy machinery.
What are the effects of surges and spikes?
Degradation: Gradual deterioration of internal circuitry from repeated power surges and spikes that slowly degrade electrical components, shortening their lifespan and making them less reliable.
Destruction: Resulting in expensive equipment repair or replacement costs.
Downtime: The most costly effect, can result in the loss of data, productivity and customers.
What equipment should be protected?
Power surges and spikes can be induced onto any type of unprotected electrical cabling, including utility power lines, network and communication lines, and low voltage power feeds. Therefore, surge protection should be installed on all critical electronic systems and the electrical paths between them.
What are the benefits of investing in quality surge protection?

INSTALLATION BEST PRACTICES
1
2
3
Conductor Length 3 ft
The conductor length between the SPD and the equipment being protected should be a minimum of three feet in length to allow enough time for the SPD to react. The conductors can be greater than three feet as long as they are isolated and are not subjected or directly exposed to internally- or externally-generated transient voltage spikes and/or surges.
Utilize separate conduit feeds
Always make sure that the field wiring (unprotected wires) and the protected wiring occupy separate conduit feeds. When unprotected and protected wires occupy the same conduit, surge energy can be induced on to the protected wiring and completely bypass the surge protective device.
Use grounding bus bars
The use of a grounding bus bar is strongly recommended as a means of terminating SPD ground wires to existing electrical grounding leads. This will ensure a solid mechanical connection of all grounding wires.
The use of twist-on wire connectors (“wire nuts”) is not recommended for termination of SPD ground wires to existing electrical grounding leads. Twist-on wire connectors can increase ground resistance, may become loose and/or corroded over time, and can also unnecessarily extend the length of the grounding conductor. This would degrade the performance of the SPD due to the lack of a short, low impedance ground path.
Use dedicated enclosures
Whenever possible, Surge Protective Devices should be installed in a dedicated enclosure outside of the equipment being protected. This will prevent physical damage to the electronic circuit board, power supply and/or wiring inside of the equipment panel due to a potential catastrophic failure of the SPD.
Use a dedicated ground wire
When installing multiple SPDs and terminating to a common electrical ground, a dedicated ground wire running from each individual SPD to a common grounding bus bar is strongly recommended. “Daisy-chaining” multiple SPD ground wires together via the SPD grounding terminals, or by using twist-on wire connectors, is not recommended as this increases the resistance and extends the length of the ground path.
