Table 3-2 Device Quantities and Loading

The particular combination of device types, external loads, cable length and type may limit the total number of devices. This is calculated in the following sections.

There are two types of load which must be considered - DC and AC. Also if isolator bases are used, the loading between each isolator base must be considered.
