Permits, inspections and the inspection authorities

In Nova Scotia, the wiring permit is where the whole system comes together. It is the point at which the Electrical Code Regulations check that a certified person is responsible, the point that triggers inspection, and the record that lets a utility connect power with confidence. A contractor who handles permits and inspections well avoids most of the trouble new businesses run into. This lesson covers who issues permits, who may hold them, what work is exempt, how inspections work, and what happens when an installation fails.

Procedures, contact numbers and fees in this lesson come from the province's regulations and Nova Scotia Power's published inspection pages and bulletins. They change. Confirm the current process with the inspection authority before you rely on any detail, and if you work in one of the six towns with a municipal electric utility, ask that utility how its process differs.

The inspection authorities

The Electrical Code Regulations define an inspection department as a public utility that supplies, or will supply, electric power and grants permits to contractors. The Act requires a public utility or an inspector to inspect a consumer's installation before supplying power, and it says utility inspections of new work must be carried out by people approved for the job. The province's electrical safety page lists seven utilities that carry out inspections: Nova Scotia Power and the municipal electric utilities of Antigonish, Berwick, Canso, Lunenburg, Mahone Bay and Riverport.

For most of the province, that means Nova Scotia Power. Its inspection pages direct contractors to its Wiring Permit Contact Centre, listed at 1-800-464-1520 from 7:00 a.m. to 6:00 p.m., Monday to Friday, for scheduling inspections, and to its mailing address at 25 Lakeside Park Drive, Lakeside, for Inspection Services. In the six towns, the town's own utility issues permits and inspects within its service area.

Above them all sits the Provincial Chief Electrical Inspector, who approves inspection procedures, sets qualifications for inspectors, issues bulletins and interpretations, and can order disconnection of a hazardous installation. If a contractor and a utility inspector disagree about the Code, the Chief Electrical Inspector is the final authority.

When a permit is needed

Section 7 of the Electrical Code Regulations requires a permit before any electrical or communications work begins, unless the regulations exempt it. The rule is simple and strict: the permit comes first, then the work. Starting before the permit is in place, even for a day, means the work was unpermitted, and covering it before inspection is an offence under the Act.

Nova Scotia Power's pages put the inspection side just as plainly: installations must be inspected before any wiring is concealed by backfill, lathing, boarding, insulation or other coverings, and the contractor arranges a final inspection when the work is complete.

Who may hold a permit

Section 8 limits electrical permits to two kinds of holder.

• An electrical contractor who is a construction electrician, or who employs one. This is the route for every contracting business.
• The owner or occupant of an establishment where routine electrical work is done frequently, if they employ a construction electrician or an industrial electrician. This is a maintenance permit. It runs for one year and requires a record of the work to be kept and made available to the inspector, and the establishment gets an annual limited inspection.

Communications permits, under section 9, go to communications technicians and construction electricians. Nova Scotia Power's pages say communications wiring must be done by a certified communications cabling specialist.

There is no general homeowner permit route in the regulations, and Nova Scotia Power states that only a person holding a valid Nova Scotia certificate in the electrical construction trade can obtain an electrical wiring permit. That is a real difference from provinces that let homeowners pull permits for work on their own houses. A Nova Scotia homeowner who wants electrical work done needs a certified electrician to take out the permit.

Work that does not need a permit

Section 12 exempts certain minor electrical work from permits, on two conditions: a construction electrician does it, and keeps a record of it available for inspection. Nova Scotia Power's pages list examples, and the regulations set the limits. In our own words, the exempt work includes:

• replacing wiring devices or equipment rated up to 30 amperes at 120 volts, or 50 amperes at 240 volts;
• installing one branch circuit of 15 to 30 amperes at 120 volts, or 15 to 50 amperes at 240 volts;
• replacing light fixtures in a dwelling unit, and replacing motors.

These exemptions do not apply in locations covered by Sections 18 and 20 of the Code, the hazardous location sections. Section 13 exempts small communications jobs, up to six cabling drops, or relocating up to 20 outlets without new cable runs or fire wall penetrations. Section 14 exempts certain installations entirely, such as security and intrusion alarm systems.

The record-keeping condition is easy to forget and important to keep. An exemption from the permit is not an exemption from the Code, and the record is the evidence that a certified electrician did the work. Aisha keeps a simple log in the company's job software: date, address, what was done, who did it, and the circuit rating.

# Is this small job exempt from a permit under section 12? (study aid only)
def exempt(kind, volts, amps, hazardous=False, count=1):
    if hazardous:
        return False, "no exemption in Section 18 or 20 locations"
    limit = 30 if volts == 120 else 50 if volts == 240 else 0
    if kind == "replace device" and amps <= limit:
        return True, "exempt if a construction electrician does it and keeps a record"
    if kind == "new branch circuit" and count == 1 and 15 <= amps <= limit:
        return True, "one circuit only; record required"
    return False, "permit required"

            ("replace device", 120, 15, True)]:
    print(job, "->", exempt(*job))

Inspections

Inspection is the heart of the Nova Scotia system. A typical permitted job has at least two inspections.

• Rough-in. Before any wiring is concealed. The contractor books it through the inspection authority and keeps the work open until it passes.
• Final. When the work is complete. Nova Scotia Power's pages say the final may cover devices, lighting and panel labelling.

Larger jobs may need plan review before work starts. Nova Scotia Power's bulletin on plan review sets out when electrical plans must be submitted for acceptance, with separate forms for general and solar submittals. Temporary power on construction sites has its own bulletin. New services involve coordination between the inspection and the utility connection, because the Act forbids a utility from supplying power to a new installation that has not passed inspection.

Inspectors and utilities have broad rights of access. The Act lets them enter premises at reasonable times to examine installations, and requires consumers and contractors to give access. It also prohibits obstructing an inspector and covering work before it is inspected and approved.

When an installation fails

An inspection that finds a problem results in a deficiency the contractor must correct before the work is concealed or connected. Most deficiencies are small and fixed the same day. For serious or ignored problems, the Act gives utilities and the Chief Inspector strong tools.

• Refusal to connect. A utility must not connect or supply power to an installation that does not comply.
• Disconnection. After notice and a deadline, a utility must disconnect a non-compliant installation unless the Chief Inspector extends the deadline. Section 16 of the regulations also lets an inspection department or the Chief Inspector order or effect disconnection of a hazardous installation.
• Prosecution. Violating the Act or the regulations is an offence. The Act sets a maximum fine of 1,000 dollars on summary conviction. That figure is low compared with some provinces, but the practical costs of refused connection, rework and reputation are far higher.

Inspectors and utilities acting under the Act are not liable for losses caused by defects in installations or equipment. The responsibility for the work stays with the people who did it.

Fees

Permit and inspection fees in Nova Scotia are not set by the inspection authorities on their own. The Act gives the regulator of public utilities the power to set fees for inspections, permits and certificates, and the regulations refer to a fee scale approved by that board, now the Nova Scotia Energy Board. Nova Scotia Power publishes a schedule of fees and refers to its approved-fees regulation and a fee bulletin. Build the permit cost into every quote, and check the current schedule rather than reusing an old figure.

A worked example: the MacKenzie farmhouse

Planning inspections into the schedule

Inspections are a predictable part of every job, so they belong in the schedule from the start. On a renovation, the rough-in inspection usually has to happen before insulation and drywall, which means it controls the other trades' start dates. On a service upgrade, the utility's disconnect and reconnect must be coordinated with the inspection, and the customer needs to know how long the power will be off.

Aisha keeps a simple rule: book the inspection when the work is ready, not when she hopes it will be. A failed inspection costs a second visit, delays the next trade and annoys the customer. Asking for an inspection a day later than planned, with the work actually finished, costs nothing.

Good records make inspections smoother. The permit number, the scope, any plans that were accepted, and notes on any questions already discussed with the inspector should be in the job file and on site. When the inspector arrives, the person on site should know the work well enough to answer questions and show anything the inspector wants to see.
