In electrical plans, PP typically stands for Power Panel. It is used to refer to a panel used for power plans. It can also be named based on the floor level the electrical room is on. For example, a panel board may be referred to as LP (Lighting Panel) or LP-17, with the number denoting the circuit number.

What You'll Learn
PP stands for Power Panel
Electrical plans are technical drawings that show information about power, lighting, and communication for engineering or architectural projects. They consist of lines, symbols, dimensions, and notations to accurately convey an engineer's design to workers, who then implement the electrical plans. Electrical drawings contain many fixtures, switches, and panels. To avoid confusion, abbreviation tables are included to explain the text written beside the electrical symbols for electrical components in a diagram.
Electrical plans include multiple drawings describing the respective layout, such as power distribution layout, panel layout, wiring layout, and fixtures layout. They represent an electrical blueprint and drawing symbol. The wiring layout consists of wiring routing and is set on a path for wires inside the ceiling, which can be seen in a wiring layout. The wiring provided to the light from the switchboard can be observed in the conduit layout with the junction box installed, referring to the drawings available at the site. The ceiling is installed once all the wiring is done.
Electrical drawings or schematic diagrams give a visual representation of electrical systems and electrical wiring for electricians and electrical engineers to utilize. They include various electrical components, like electrical outlets, fixtures, switches, lighting, fans, and appliances.

PP distributes large electrical loads
In electrical plans, PP typically stands for Power Panel. It is used to distribute large electrical loads. Power Panels are also known as Load Centres or Breaker Panels. They are used for all receptacles and larger equipment.
PP is used to refer to a panel used for power plans, as opposed to LP, which stands for Lighting Panel. Engineers tend to name panels based on their use, so a panel primarily used for lighting might be LP or LP-A, while a panel used for power plans will be called PP or PP-A.
The number after the LP or PP designation refers to the floor level the electrical room is on, or the circuit number in that panel. For example, LP-17 with an arrow means a home run to panel space #17.
In renovations or smaller jobs, where separate panels are not justified, the LP and PP designations can be mixed. However, it is important to note that the LP/PP designation is just the name of the panel and does not always indicate the specific breaker that should be used.

PP is crucial in industrial facilities
PP, or Power Panel, is crucial in industrial facilities. It is a term used in electrical plans to refer to power plans.
Polypropylene (PP) is a commonly used thermoplastic with a wide range of applications in industrial facilities. Its lightweight and durable nature makes it ideal for automotive parts, such as bumpers, interior trim, and battery cases. Its electrical insulation properties make it suitable for electrical and electronic components, and its chemical resistance is advantageous for industrial filters and corrosion-resistant components.
PP's versatility extends to the medical field, where it is used for syringes, IV components, and medical packaging due to its biocompatibility and sterilizability. In industrial settings, PP is used for pipes, tanks, and chemical containers. Its low moisture absorption and good mechanical strength make it suitable for outdoor use and damp environments.
The versatility, durability, and cost-effectiveness of PP make it a popular choice for a wide range of industrial applications. Its ability to be 3D printed further enhances its versatility, making it a crucial material in modern industrial facilities.

PP is a central hub
In electrical plans, PP stands for power panel. It is the central hub for electrical power distribution in a building. All the electrical circuits in the building originate from the power panel, which is why it is considered the central hub.
The power panel is usually located in an easily accessible area, such as a utility room or basement, to facilitate maintenance and repairs. It typically consists of a large metal box that houses the electrical service head, the main service disconnect, and individual circuit breakers.
The electrical service head is where the electricity enters the building from the utility company's power lines. It contains a meter that measures the amount of electricity consumed, and this information is used by the utility company to calculate the cost of the electricity used.
The main service disconnect is a large switch that allows the electricity to be completely shut off from the building in case of an emergency or when maintenance work needs to be performed. This is usually located at the top of the power panel, with the individual circuit breakers below.
Each circuit breaker controls the electrical flow to a specific area or circuit in the building. They are designed to trip and shut off the electrical flow to a particular circuit if it becomes overloaded or if there is a short circuit, helping to prevent electrical fires or damage to appliances.
The power panel is an essential component of any electrical system, and its central hub status ensures that electricity can be safely and efficiently distributed throughout the building. It provides a convenient and accessible location for managing and maintaining the electrical circuits, allowing for quick identification and resolution of any issues that may arise.

PP is used to mean peak-to-peak
PP can stand for power panel in electrical plans. However, in the context of electrical engineering, the abbreviation "p-p" is used to mean "peak-to-peak".
Peak-to-peak refers to the total level from the top to the bottom of a wave. It is the sum of the magnitude of the positive and negative peaks of a waveform. In other words, it is the full voltage between the positive and negative peaks of the waveform.
Peak amplitude (Vpk) is from the midpoint to the peak of the wave, whereas peak-to-peak (Vp-p) is from the peak to the bottom of the trough.
In spec sheets, "p-p" typically refers to direct current, although there are other specifications that specifically use "Vdc" to denote direct current.

Frequently asked questions
PP stands for Power Panel.
A Power Panel is used for all receptacles and larger equipment.
Other types of panels include Lighting Panels (LP) and Load Panels (LP or LP-A).
Engineers try to keep things simple by naming panels based on their use. A panel primarily used for lighting might be called LP or LP-A, while a panel used for power plans will be called PP or PP-A.
The number after "LP" refers to the circuit number in that panel. For example, LP-17 with an arrow means a home run to panel space #17.
