4.3.2. When laying out the location for the Emergency Lighting Inverter system, DSPM recommends adheres to the
National Electrical Code (NEC) and/or the local code in your area. Ideally, all the Battery Cabinets are positioned
the same distance from the ELI, making the gauge of the cabling the same (local code) from each battery cabinet.
When battery cabinets are unequally spaced throughout your facility use the two size larger rule. The two size larger
rule is to use cables that are two sizes larger for cabinets that are two times (2X) the distance away from the ELI.
For example in Figure 5, the distance from the ELI to the right end of the third battery cabinet is 135 inches. If the
NEC and/or local code calls for a #8 gauge cable to make the connections to these three battery cabinets, then the
second set of three cabinets (135 inches further away from ELI) use #6 gauge, and the nal two cabinet should use
a #4 gauge.
Using Figure 5, another approach that can be used is to take the ELI and center it between the four pairs of battery
cabinets and maintain the same distance and wire/cable size.
