<strong>NECA</strong> <strong>400</strong>-<strong>200X</strong> – Reballot Draft<br />

b) Forklifts: Forklifts are an alternate method of handling<br />

switchboards. Verify that the capacity of the forklift is more than the<br />

weight of the load to be lifted. Always insure that the form lengths<br />

extend under the entire switchboard and extend beyond the<br />

opposite side (see Figure 3).<br />

c) Rollers: If equipment is not available for lifting the switchboard, or<br />

the ceiling is not high enough, rollers suitable for the application<br />

may be used to move the switchboard into position. A forklift or<br />

jacks can be used to initially lift the switchboard and position it on<br />

the rollers. Rollers should be positioned approximately every 18<br />

inches (457 mm), and be at least the width of the switchboard for<br />

stability. Extreme care should be taken when using rollers due to<br />

switchboard height and weight. Rollers are most suitable for<br />

moving switchboards on a level surface; use a winch or chainfall<br />

where inclines must be traveled over to prevent “runaway.”<br />

2.2 Storing the Switchboard<br />

a) Cover the switchboard with a tarp or plastic to keep the equipment<br />

from getting wet and accumulating dust or debris (cement dust can be<br />

corrosive and cause insulation breakdown when it accumulate across<br />

insulators). The cover should be heavy enough to keep from tearing<br />

during wind gusts at the storage location.<br />

b) To reduce condensation within the switchboard, store the switchboard<br />

indoors whenever possible to keep harmful condensation from<br />

accumulating inside the enclosure.<br />

c) Install a minimum of 250 watts of heat per vertical section, even for<br />

outdoor enclosures. Remove all loose packing or materials that could<br />

catch fire prior to applying the heat.<br />
