Most construction projects will have a mandatory timeline so that the project can stay on track.

The building summary includes important information that applies to the electrician&rsquo;s installation.

The occupancy classification must be known before planning the wiring methods to be used.

Group A-3 can include places of religious worship.

A testing laboratory is a group B occupancy.

An educational occupancy includes the use of a building or structure, or a portion thereof, by six or more persons at any one time for educational purposes through the 12th grade.

Hospitals are Group I occupancies.

Hotels are R-1 occupancies where the occupants are transient in nature.

A hotel with conference rooms and a gift shop is an example of a mixed use occupancy.

IBC table 601 provides the fire-resistance rating requirements for building elements (in hours).

IBC table 601 provides the fire-resistance rating requirements for building elements (in hours).

Many restaurants and churches are built using heavy timber Type IV construction.

Type V construction is the most common construction type for residential dwellings including single family homes.

When penetrating a rated wall, floor, or ceiling assembly design, care must be taken to follow the exact requirements set forth in the through penetration firestopping design specified in the plans.

Newer buildings are required to have markings on fire rated walls to alert those about to make a penetration.

These nonmetallic electrical boxes are installed as membrane penetrations through a fire-rated separation wall between two apartment units and are protected by listed putty pads.

When installing a recessed luminaire into a rated ceiling, one option is to use a luminaire enclosure that is listed for use in a fire resistance&ndash;rated construction.

The final inspection shall be made after all work required by the building permit is completed.

Always ask the electrical engineer for permission before detouring from the approved plans.

Dedicated space for the panelboards is insufficient now that the ductwork has been installed and wrapped.

Typical light pole base detail and installation.

PVC electrical conduit is too shallow, improper 90-degree fitting used, backfill material full of rocks that could damage the conduit.

The rough wall electrical inspection should be ready before the inspection is requested.

Make sure all temporary lighting has been removed from the above ceiling space before the ceiling tiles are installed.

This inverted disconnect switch is a violation of the installation instructions and the manufacturer instructions.

A written record shall be kept of tests and maintenance. The tag on this Unit Equipment shows when the luminaire was last tested.

All boxes and enclosures (including transfer switches, generators, and power panels) for emergency circuits shall be permanently marked as a component of an emergency circuit or system.

Selective coordination is required between breaker &ldquo;XYZ&rdquo; and the next downstream overcurrent device in the nonemergency system.

A battery equipped emergency light with a UL 924 relay is an example of Unit equipment.

NEC Section 700.12(I)(2)(3)(b) was used for this example.

Emergency illumination includes means of egress lighting.

A single LED emergency luminaire above an exit door. Is it compliant with 700.16(B)?

Unless this HID metal halide luminaire has a quartz restrike, the emergency luminaire must have a time delay feature.

Since this building has an emergency system, emergency lighting is required for the interior service disconnect.

The IBC requires emergency illumination for specific rooms and spaces.

Be mindful of important information on other pages in the plans that may not be electrical related.

Always check the luminaire schedule for the type of luminaire and number of required lamps.

The design engineer may have gone to great lengths to ensure proper illumination levels when putting the plans together.

The design engineer should include mounting height of emergency luminaires on the plans.

Installing the emergency luminaires higher than the installation instructions allow will result in less illumination at the walking surface and a red tag from the inspector.

Be sure to coordinate with the inspector if there will be items shown on the plans that cannot be installed before the final inspection.
