Neutral grounding devices (resistors) are used to control the ground-fault currents and voltages to ground of alternating current systems. Earlier versions of the Canadian Electrical Code restricted the use of neutral grounding devices to systems that supplied only 3-phase loads (no single-phase loads). But the 2006 Canadian Electrical Code was revised to change all of that. Now single-phase loads are permissible with conditions.

Design and installation of electrical equipment is a reasonably well understood and adjusted procedure. It is done in accordance with the safety requirements of the Canadian Electrical Code and specific installation standards, with additional performance criteria of energy codes, ASHRAE codes and regulatory directives, and undoubtedly — with particular requirements of the clients. Of course, such installations are inspected by the electrical safety regulators for compliance with the accepted design and with the CE Code provisions.
(No Ratings Yet)The term supply-side bonding jumper first appeared in the 2011 National Electrical Code as a result of a CMP-5 Task Group regarding the proposed revisions to Section 250.30 for grounding separately derived systems.
(No Ratings Yet)In this instance, the panelboard is serving the function of a pull box for these pass-through conductors.
(No Ratings Yet)Yes. Convention center cord sets are required to be constructed with cord that is evaluated as being equivalent to extra hard usage or “Type S” cord.
(No Ratings Yet)Yes. A few manufacturers have had their electric vehicle DC fast chargers UL certified. Electric vehicle DC fast chargers can fully charge an electric vehicle battery in as short as 15 to 30 minutes. These fast chargers will most likely be installed at electric vehicle charging locations in public/commercial settings, such as traditional gas or service stations.
(No Ratings Yet)While real energy savings are being generated by solar photovoltaics markets in the U.S. and many American homeowners are excited about reducing their electrical costs, most of them lack funds to install the units on their roofs. Consequently, the DOE is funding a program to reduce the costs of solar PV installations.
(No Ratings Yet)Whoever would think of Shakespeare and electrical inspections together? Throughout the preparation of this issue, my thoughts kept returning to the Bard’s definition of being real, “This above all: to thine own self be true, and it must follow, as the night the day, thou canst not then be false to any man.” It seems that many of our writers are asking how we as members of IAEI can be real to our communities and clients.
(No Ratings Yet)Question Where conductors from both dc and ac photovoltaic systems utilize a common junction box or other enclosure, are there any special identification requirements for these conductors? Also, where photovoltaic circuits are run inside a building (whether in conduit or not), can these circuits be run embedded within insulation, and if so, is there any [...]
(No Ratings Yet)A single or duplex receptacle is acceptable in this situation. Section 210.52 addresses the requirements for dwelling unit receptacle outlets.
