Study Notes
Electrical Code Requirements
- Fluorescent light fixtures supported independently of an outlet box must be connected by a metal raceway, nonmetallic sheathed romex cable, or a nonmetallic raceway: all of the above are acceptable.
- Service entrance equipment includes panelboards, meter enclosures, and service disconnecting means.
- Medium voltage cable insulation is rated for 2001 volts and higher.
- Single-phase loads connected to the load side of a phase converter should not be connected to the high leg.
- A 480 volt motor with a full-load current of 34 amperes requires a standard disconnecting means of 40 amps.
- For a 150 square meter single-family, one-bath dwelling with a calculated neutral load of 14550 VA, the calculated load for the neutral is approximately 77.5 amps.
- A 12 kW range in a 145 square meter single-family, one-bath dwelling requires two 2-wire 20 amp circuits.
- If building "A" is supplied with 120/240 volt single-phase power from building "B" on the same property, where "B" is supplied from a three-wire system with two ungrounded conductors and one neutral, the neutral conductor must be bonded to the disconnect enclosure in the second building and connected to a grounding electrode.
- A copper THHN feeder conductor with 40 amps of continuous load, 35 amps of non-continuous load, and three current-carrying conductors in a raceway with terminations rated at 75 degrees C requires a minimum overcurrent device of 86 amps.
- Wiring installed to meet the minimum electrical code requirements must be safe and free from hazards.
- The lowest point of the drip loop of a 208/120 volt, 3-phase, 4-wire electrical system must have a minimum clearance above a pedestrian sidewalk of at least 1900 mm.
- The grounding electrode conductor connection to a driven ground rod must be accessible, directly buried, and should not require accessibility by wire taps.
- Photovoltaic system currents are considered to be continuous currents.
