Pad-mounted capacitor banks can be installed both indoor and outdoor, depending on the enclosure design. Indoor installation plans are not always provided, so it's essential to check the enclosure design for suitability. Anchor bolt plans (Figure 2) are furnished with the capacitor bank assembly drawings.
The conductor used to connect the capacitor bank to the system should have a continuous current rating of at least 35 percent more than the nominal current rating of the bank. (The current rating of the bank is the value given in the question)
Pad-mounted capacitor banks ( suitable for indoor or outdoor installation ) are described in the installation instructions (Figures 1 and 3). Their enclosures are typically constructed using mild carbon steel with a powder coating.
