From code enforcer to code interpreter, problem solver to referee, to public relations representative, it can be challenging to keep track of the many hats electrical inspectors needs to wear!
Can a panelboard be located “you fill in the blank?” How often have you heard this question? Let’s take a look at some of the rules on panelboard placement contained in the National Electric Code (NEC).
To support the ongoing construction of shelter and to maintain existing shelter, we must keep the infrastructure working. We must keep the electricity, gas & water flowing. Grocery stores and fueling stations must be kept open. Inspection by the Building Department is involved at some point for all of these critical functions.
How do we as electrical professionals promote the need for this electrical working space so that panelboards remain readily accessible?
In order to truly understand the implications of the changes to the measuring provisions of Section 210 in the 2020 National Electrical Code (NEC), one must go back and review how we arrived at that point.
Our role as inspectors plays a vital role in assuring that homeowners and the public are safe from electrical hazards. Being an informed inspector by knowing what the NEC says and why changes occur is critical to your continued role in this process.
Let’s look at the basics of a grounded 480/277 V to 208/120 V wye-type transformer supplying a panelboard in a typical retail or office space.
The challenge is getting people out of flammable clothing and into appropriate PPE through code guidance that’s easier to understand and implement. It starts by putting ourselves in a contractor’s shoes.
For example, today’s Code requirements state that an intentionally grounded conductor (sometimes referred to as a neutral conductor) is required to be installed at all switch locations where switches control lighting loads that are supplied by a grounded general-purpose branch circuit, or are they?
My two weeks spent doing field inspections involved long days and many stories. As a volunteer, I was always well received by the people of New Orleans.
