Generator Installation Requires a Site Survey and a Licensed Electrician

The installation of a standby generator requires licensed tradesmen, such as plumbers with experience working on outdoor gas lines and electricians with experience installing generators and transfer switches. Some areas may require a concrete pad for the generator to sit on.


Proper generator placement is vital for ensuring the system meets safety standards, adheres to local noise regulations and aligns with aesthetic preferences. A good contractor will handle the permit process for you. Contact Generator Installation In Spring TX for professional help.

A site survey is an examination of a location or spot for data or information that will be used to create plans and specifications. A site survey may involve several different techniques and factors, depending on the type of plan that needs to be executed.

Before any work can begin on a generator installation, it is important to have a thorough site survey completed. This process involves examining the premises, taking measurements, testing equipment and making note of any special conditions or safety considerations. The results of the site survey will help ensure that all equipment is installed correctly and that there are no problems down the line.

If the customer or stakeholder is present during the site survey, it can help to speed up the process and also provide them with a more accurate picture of what will be included in the project. This can lead to fewer revisions later on in the process, which can save time and money. It can also give the customer or stakeholder a better sense of trust and transparency, which is always beneficial.

During a site survey, it is a good idea to walk the premises with your customer or stakeholder and collaborate on where each device should go. This will help them feel involved in the project from the start and also allow them to see a valuable digital map being created for devices that they can use throughout the life cycle of their system.

The survey will also include a list of any potential obstacles and risks that could impact the project. This will help the team drafting the blueprints identify ways to mitigate these issues, which can reduce costs and timelines for the overall project. It can also reduce the number of unexpected issues that will arise during construction, which is a major cost-saving measure for any project.

Another aspect of a site survey is to make sure that any existing utilities are properly connected and that all relevant permits have been obtained. This will help the contractor avoid any issues that could delay or even derail the project. If any issues are encountered, the contractor will be able to notify the customer of potential delays or additional charges and discuss ways to address them.

Electric Permit

Many homeowners install standby generators to provide backup power in the event of a utility outage. These systems must be connected to the household electrical service panel through a transfer switch. A permit is required to perform this type of work, and a licensed electrician must be hired to complete the installation.

The permit application must be completed and submitted with the required fee. A copy of the survey or site plan must be included, showing the location of the generator and the existing electric meter. In addition, a UL-listed transfer switch and panel board must be used. Load calculations must be provided, indicating the total generator capacity, and demonstrating that this load will not exceed the service capacity of the home.

Other technical information that is required to be provided includes stack parameters, equipment details, maximum heat input/output, EPA tier, and emission estimates. A photograph of the generator must also be included. If the generator is running on propane gas, a Propane Tank/Lines Permit must be filed as well.

Depending on the scope of work, an Electrical Special Permit may be needed. This will be determined by the DOB electrical team. The electrical permit review will be done concurrently with the plumbing and generator permit.

If the scope of work consists solely of installing a residential standby generator, an Electrical Permit can be applied for. If the project involves the installation of a new service, that should be applied for on a separate Electrical Permit with a New Construction Parent Building Permit.

Prior to beginning any digging, the homeowner or contractor must call Miss Utility at 811 from a land-line telephone, or 1-800-889-7650 from a mobile phone, to have the underground lines marked free of charge. This is a state law that must be followed, to avoid damaging utility lines and potentially costing the homeowner in fines or repairs. Once the work has been performed and the permits have been issued, a final inspection must be scheduled. This inspection is to ensure that the generator and associated wiring comply with the requirements of this permit, and that the system will function properly when activated for use.

Plumbing Permit

A plumbing permit is needed for the installation of any new plumbing fixtures and piping. Depending on the scope of your project, this may include anything from changing toilets to replacing sinks or faucets. Licensed professional plumbers should be able to determine whether a permit is required for your project before getting started.

National plumbing codes provide general guidelines for plumbers, but local county and state regulations will likely supersede these standards. You’ll need a permit if you’re adding, repairing or replacing any plumbing fixture or piping in your home or commercial property.

There are some cases in which a plumbing permit is not required, such as ordinary minor repairs that do not alter the existing plumbing system. You’ll also need a plumbing permit to replace or repair water heaters, drain traps, and venting systems. This type of work typically requires a plumber who is certified in that particular mechanical class and holds a valid contractor license.

Other permits that are commonly associated with plumbing projects include:

Water and sewer utility permits — These are typically needed when working on the piping that brings water and waste into your building or structure. You’ll need to submit full plans and drawings before being granted a water and sewer permit.

Mechanical permits — These are needed when installing mechanical equipment like pumps, valves, water heaters, ventilation, medical gas equipment, and more. They’re generally issued to professionals and licensed master plumbers with a valid mechanical contractor’s license.

Plumbing/Hydro-Electric Connection Permit — This is needed when connecting or disconnecting a building or structure to a public water and sewer service. You’ll need a professional engineer or licensed master plumber to submit detailed plans and drawings before being granted this permit.

The permitting process can be complicated, and it’s important to follow all the rules and regulations set by your city and state. Licensed professional plumbers should be familiar with these requirements, which will save you a lot of time and hassle. They’ll be able to navigate the process quickly and ensure that your job is done properly in accordance with the law.

Transfer Switch

A transfer switch is the key piece of equipment that connects your generator to your home or commercial building. It allows you to easily power essential appliances and systems during a power outage by flipping a switch. Depending on the type of generator you choose, your transfer switch may have either manual or automatic operation.

Manual transfer switches are permanently installed near the circuit breaker, and you must manually start up your generator, wait for it to stabilize, and then flip the switch to the generator position. This requires more effort than an automatic transfer switch, but it can be less expensive and more robust.

An automatic transfer switch detects a power outage, activates the backup generator, and then switches the loads from the utility to the generator. This can take only a few seconds, making it ideal for facilities that cannot afford to lose even a few minutes of production. When utility power is restored, it also reconnects the loads to the grid and shuts down the generator.

Both types of switches have advantages and disadvantages, so it’s important to understand your needs before selecting one. A transfer switch should be rated to match the power capacity of your devices and appliances, so add up their combined wattage or amperage before choosing a switch. You can find a variety of options for both single- and three-phase systems. Consider the enclosure type, too, as some are made to withstand indoor or outdoor environments.

Closed transition transfer switches are also available. They work in a break-before-make mode, which eliminates the gap that exists between the electrical disconnection and connection when transferring power to a backup generator. This makes code-mandated monthly testing of the transfer switch easier and more streamlined. It can also reduce the risk of backfeeding, which can put utility workers at risk and cause damage to your appliances or systems.
