Installation height of electrical distribution box in tunnel construction
Typically a 5' 110V fitting, spaced every 10 metres, installed at a height of 3M in a 4M diameter tunnel, will provide an average illumination level of 15 to 20 lux. A design of this type would require a transformer every 400 metres with the transformer locat-ed at the. This FHWA manual is intended to be a single-source technical manual providing guidelines for planning, design, construction and rehabilitation of road tunnels, and encompasses various types of road tunnels including mined, bored, cut-and-cover, immersed, and jacked box tunnels. Main LV supplies into tunnels are often provided with a back-up stand-by generator and our Mains Distribution Assemblies (MDAs) can incorporate Manual or Automatic Changeover systems to switch between Mains. The following table shows the relation between size and height of p ire should be installed to balance the pole.
