"Inspecting Commercial Electrical Systems"

I know how it’s an awesome game so I real want to Play it haha :slight_smile: :slight_smile:
tank trouble

Image Assignment:
I have an image of a receptacle that is missing it’s cover plate and was not properly secured to the electrical junction box.
Upon further investigation it was found that the wires going to the receptacle were live.
This is an electrical shock safety hazard that requires immediate repairs by a qualified electrical contractor.
Before leaving the office I located the breaker for the receptacle and switched it off. I also tagged the breaker so that it would not be switched back on until repairs to the receptacle were completed.

Research Assignment:
I did my research assignment on fire alarm systems. I was fascinated to learn that older fire alarm systems may not be reliable even though they are maintained. Fire alarm systems that are older than fifteen years and properly maintained may continue to work satisfactory but some of the components may be beyond their technological life expectancy. Testing and inspecting the fire alarm systems by trained professionals is the only sure way to know that the older fire alarm system will response properly in case of an emergency.

This image shows a kiln furnace located at the art department of a local college.
I was called and asked to do an inspection of the art department of Berry College, here in Rome, Ga. In particular this kiln was found to be in a very dangerous condition. It was actually built by the art students 25 years ago and had received very little maintenance over the years. The thermocouples were broken off of there brackets that held them into place at each burner. The students bent the capillary tube so that the thermocouples would be positioned within the flames of the burners. There were several places in the brickwork where brick were missing, allowing exhaust gases to escape around the kiln chimney. I found several gas leaks and issues with the roller doors not closing properly. The temperature gauges were improperly wired in the control panel and the emergency switch had been bypassed. When I issued the report on the kiln, I suggested shutting it down until repairs were made. The college decided to buy a new kiln for the art department. The Dean was very appreciative in finding these issues, the students didn’t want to shut it down, that’s why they kept running it as it was. It all worked out for the best.

For my reading and essay assignment I chose the “Performing Commercial Inspections” article.
It’s interesting to find out from the article that not so many inspectors are doing commercial inspections. I come from an industrial background and have always enjoyed watching production equipment operate.
I wonder though if many of the commercial purchases made even call for an inspection. I have done several for mortgage companies and for local colleges. I have five commercial property inspections scheduled for next week. So it has picked up for me recently. I have printed off the Cominspect application to join their network.
I plan to take several more commercial courses in the future.
Thanks for doing a good job.

This photo is from a mobile home parks sewer sub station area. The power source is overhead to this point. Power comes down the pole goes under the ground and is feed back up to this location. It leaves this station going back under the ground. The station is equipped with a red light alarm system. You can also see in photo that their is a locked man hole cover. This is for service companies. This station has the power companies meter along with a few different panels controlling power to several different pumping machines and other powered components.

" Electrical Terms "

When it comes to electrical systems their is so much to learn and continuing education to keep up with ever changing codes is important. As a home owner or an inspector we all need know some basics to stay safe and to be able to understand electricity. Voltage is the measure of potential energy per unit of charge. Resistance is the measure of restriction of flow of the current through a material. Amps are a measure of electrons flowing in the same direction. Power is a measure of the overall work being done in a system. In electrical systems all the different measures are dependent on one another.

A picture of a receptacle on an exterior outside wall with no Gfci cover or Gfci protection.
The receptacle box is also not outdoor rated and will allow water to get into the box.

Interesting article I read on baghouses. They are used in commercial buildings to help purify air in commercial building that manufacture steel, food and other dust forming processes.
They essentially work like a huge shop vac.

Noted an ANSUL fire suppression system installed above the cooking stations in the commercial kitchen. The system is comprised of sprayers above each station with the manual actuation button located next to the exterior door on the back kitchen wall. The system should have an annual inspection and testing of the system by a qualified contractor specializing in fire suppression systems.

I found the information regarding the differences between the typical high voltage electrical systems found in commercial properties compared to lower voltage electrical systems we normally inspect during a standard residential home inspection interesting. Specifically the expertise required to properly inspect high voltage systems and that OSHA requires that only a qualified electrical contractor can remove the covers as opposed to being able to remove the dead front covers on residential panels for a more thorough inspection of the wiring. Shows the importance of bringing in third party experts as part of doing a commercial inspection.

Taking the commercial electrical class I’ve learned a lot about high voltage.I will leave that to the guys that know that stuff.

Electrical service panels
these panels can be very dangerous.Always be able to get back if you have a problem such as a spark or bees.

Written assignment:
This commercial Rheem roof top unit (RTU) was in goof visible condition and operating at the time of the inspection. The interface with the duct system and roof was raised a few inches to reduce problems from standing water which I thought was either a ‘good practice’ or should be code. No corrosion or damage observed. The condensate line could have been run lower and further from the unit. Shutoff box, conduit, and fasteners were all in good condition and there was a service receptacle in the vicinity. Combustion air was not obstructed and combustion gas was vented properly away from other restrictions or hazards. Data tags were legible indicating a relatively new unit. Maintenance schedule was documented.
InterNACHI, note that I was unable to view the last two videos. Server problem refused to let the ‘dentist office inspection’ play past the 2 minute mark and the video after that would not play at all.

Research Assignment: Performing Commercial Inspections
One way to view a large commercial inspection that will not be accomplished by yourself is to think of it as a general contractor (GC’s) job. You may oversee a few or many additional subcontractors with expertise to inspect one component of system of the building (e.g. elevators). A commercial inspection is part of the due diligence of the buyer or investor and when they hire you, the inspector, they are seeking as much knowledge about the building as possible, to finalize negotiations and complete the transaction. The same process is often done with high-end luxury/estate type residential real estate. Sometimes this process will begin with a preliminary inspection by the general inspector to determine what additional subcontractors will be required, what the expectations of the client are, and an opportunity to review documents and records, so that an appropriate quote and temporal estimate can be given.

This inspection is a residential panel, Square D 200 amp, 40 breaker capacity with a back-up generator interlock breaker plate.

The panel is clearly marked for each breaker, the main disconnect and the generator. The conduit for the generator conductor is schedule 40 electrical and is supported above requirements.

The conduit crosses the garage ceiling, travels down the opposite wall and enters under the house through the rim joist (our local term) and continues across the house and exits into the weatherproof receptacle. A very nice installation.

Commercial Office Checklist

The article lists a number of considerations for expanding your business from a home office to a brick and mortar operation.

I nodded in agreement with the points made by Mr. Gromicko and Ms. Tarasenko because I went through the same issues for my construction and inspection businesses.

Although, it was much more intricate between 1981 and 1995 when I founded a software company that grew to 250 employees and 10,000 square feet of production space.

Hi there, These are sample images of ballasts / condensing line in the walk-in cooler for less than 2500 suare feet small convenience commercial building without residential dwelling.
Condensate water in the walk-in cooler was appeared water drop / stains along the condensing line and also shows evidence of exposed splicing electric wires besides ballasts without safely cover in the walk-in cooler.

Hi, I will post what I’ve learned regarding the Commercial and Home Inspector Safety. Commercial and residential inspectors know that facing potential dangers of their inspections is an inherent risk of the job. Inspectors must also maintain awareness of their exposure to various materials within the systems and components of the buildings they inspect that can lead to adverse physical reactions.
If a home or commercial property has components that contain hazardous substances, It’s important to update and realize such information as more threats are uncovered hazardous substances including chemical irritants and respiratory materials. Homeowners / inspectors should find out and understand where their indoor and structural components come from and opt for high-quality, eco-friendly products.
