Rating or setting of the branch circuit overcurrent protection device. The last item to cover for 225 is 225.40 Access to Overcurrent Protective Devices, which covers the situation where one may not have ready access to the feeder overcurrent device. The service requires full JavaScript support in order to view this website. When that tenant does not have access to the feeder overcurrent device, the code requires that branch-circuit overcurrent devices shall be installed on the load side of the feeder, that they shall be readily accessible, and a key point here they shall be sized smaller than the feeder overcurrent device. How Long Does a Ballast Last? A continuous load is one where the maximum current is expected to continue for ___ hours or longer? (E) Different Characteristics. 1. Moving on to 225.11 through 16 we find requirements for conductor entrance and exit from buildings, open conductor supports, spacing, supports over buildings and attachment to buildings. Small-appliance load = 2 1,500 VA = 3,000 VA, First 3,000 at 100% = 3,000 3,000 VA, Balance at 35% = 8,700 35% = 3,045 VA, Total 6,045 VA.

Table 220.42 Lighting Load Demand Factors (See NEC and supplied table for complete NEC text of table). Over 600 volts requires a minimum of 6 AWG copper, or 4 AWG aluminum, individual conductors; if using a cable assembly, the limits go down to 8 AWG copper or 6 AWG aluminum. This further supports the idea that services and outside feeders and branch circuits have many conditions which are the same. Depending on the voltage, over 600 volts or below, we are limited to how small the conductor is that may be used for these spans. A Detailed Explanation. It has been fun to work with Andrew and apply his incredible knowledge to our content.
