It’s important to note that although temporary power cabling has an insulation jacket protecting the cable from shorts, applying power still creates a magnetic field around the cable. Three-phase power cabling consists of four or five conductors: one for each of the three phases (typically referred to with the letters A, B, and C), one ground, and, in some applications, a neutral. When routing three-phase temporary cabling, the best practice is to leverage the triangular triplex method in laying out the cable. In addition, consider the temperature of the surface that the cable is on, particularly for high-capacity load-bank testing or power generation applications. A typical 4/0 type W cable has a rating of

That is important, since temperature ratings for cables are based on their operation in free air. Both options help minimize the risk of the cables overheating by providing a lower ambient operating environment. When possible, route temporary cable in shaded areas outdoors or, if it’s an option, place cable runs inside where the temperature can be controlled. In this example, another option would be to add a larger load bank to apply additional load, thus compensating for the voltage drop. If an application makes it impossible to have shorter cable runs - for example, if a load bank is outside with a connection point inside a facility - it may be necessary to add cables in parallel to decrease the resistance in the cable run. Longer cables pose the risk of voltage drop between the power source and the load. Minimize the length of the cable runs whenever possible - 50 to 100 feet is optimal.

Since temporary power needs can vary greatly from one mission critical facility to another, there are a multitude of additional uses for temporary cables and varying means to route and manage them. Load banks also support Level 5 commissioning, integrated systems testing (IST), for data center facilities. When commissioning a facility, particularly during Level 4 commissioning, installing temporary cables and load banks allows for the testing of individual components, such as power distribution units (PDUs) and backup generators. At the end of construction, during the commissioning phase of data center facilities, temporary power cabling is necessary for installing load banks to simulate future electrical and heat load that will eventually be in place once servers have been installed.

This equipment may be needed for building construction, facility commissioning, routine facility maintenance, emergency equipment failures or to restore redundancies in the event of an unexpected outage. Temporary cable can be used to connect a variety of equipment in mission critical facilities, such as backup generators, load banks, electric heaters, chillers, cooling towers, air handlers, and other electrically powered equipment.
