Overcurrent and overload protection. Where is the ground-fault short-circuit protection for the tap? The OCPD is protecting the feeder ahead of the tap. The NEC defines a tap conductor as a conductor, other than a service conductor, that has overcurrent protection rated more than the ampacity of a conductor. See Sec. 240.21 (A) and Sec. 240.21 (B) for details [240.2], as .These tap conductors shall be protected from physical damage: if overhead, by elevation and other rules in Article 225; if underground, by Section 300-5 requirements.All taps permitted by Section 240-21 (a) through (g) provide short-circuit and ground-fault protection to some degree by virtue of overcurrent protection ahead of the taps. Let’s look at .

Rule 14-100 begins by stating the obvious — that all electrical wiring must have overcurrent protection set at a level that prevents load currents higher than their rated .
One such rule states that you must protect conductors against overcurrent in accordance with their ampacity (240.4). In addition, you must provide an overcurrent protection device (OCPD) in each ungrounded circuit conductor at the point where the conductors receive their supply (240.21).NEC 2014 edition electrical code tap rules The NEC article dealing with overcurrent protection of feeder taps is article 240.21(B). These rules are often referred to as the NEC “tap rules”. There are five tap rules related to feeder circuit taps: − Taps Not Over 3 m (10 ft.) Long − Taps Not Over 7.5 m (25 ft.) LongOvercurrent protection must be provided for each phase conductor at the point where the conductors receive their supply except as permitted by 240.21(A) through (H). If you think about this for a moment, you see that the feeder overcurrent protective device (OCPD) is oversized for the tap conductor.Overcurrent protection and feeder taps - A review of NEC 240.4 outlines the overcurrent protection requirements for general building wiring conductors. The overcurrent protection requirements for feeder tap conductors are found in NEC 240.4(E)(3).
Key Takeaways: Overcurrent Protection • NEC 240.21, with some exceptions, requires overcurrent protection in each ungrounded conductor where the conductors receive their supply. • Feeder tap conductors serving downstream equipment cannot supply a second tap without additional overcurrent protective devices.

The NEC defines a tap conductor as a conductor, other than a service conductor, that has overcurrent protection rated more than the ampacity of a conductor. See Sec. 240.21 (A) and Sec. 240.21 (B) for details [240.2], as shown in the Figure.These tap conductors shall be protected from physical damage: if overhead, by elevation and other rules in Article 225; if underground, by Section 300-5 requirements.

All taps permitted by Section 240-21 (a) through (g) provide short-circuit and ground-fault protection to some degree by virtue of overcurrent protection ahead of the taps. Let’s look at each to determine the effectiveness of this overcurrent protection. Rule 14-100 begins by stating the obvious — that all electrical wiring must have overcurrent protection set at a level that prevents load currents higher than their rated ampacities. But the rule also goes on to permit some very well defined exceptions, which will .
One such rule states that you must protect conductors against overcurrent in accordance with their ampacity (240.4). In addition, you must provide an overcurrent protection device (OCPD) in each ungrounded circuit conductor at the point where the conductors receive their supply (240.21).
