GIS RMU Components

* GIS = Gas Insulated Switchgear
* RMU = Ring Main Unit
* The gas type used in GIS is SF6

* The gas is secured in a stainless steel tank and contains the following:
- The busbar of the panel.
- All live switching components


* The number of compartments in RMU depends on no. of In/Out Cells

Duct Smoke Detector

The Duct smoke detector detects smoke and combustion products in air moving through HVAC ducts.

This device prevents air handling systems' smoke recirculation in areas.

It can be connected to the fire alarm system or the BMS system.

What is the contactor?

A contactor is an electromechanical switch whose function is to make or break the connection between the power supply and the load.

It consists of Coil, Spring, Steel Core, Static Contacts, and Dynamic Contacts.

It is electrically controlled by applying a voltage to its coil and is usually powered much lower than the switched circuit.

It is most commonly used with electric motors and lighting applications.

Circuit Breaker Types in Low Voltage Systems

We have three different types of circuit breakers as follows:

1- Miniature Circuit Breaker or MCB:
Usually, we find it in the final electrical distribution boards; it can be one pole, two poles, three poles, or four poles.

Also, we can use it as a protection circuit breaker in the control panels.


2- Molded Case Circuit Breakers or MCB:
Usually, it will be as the main breaker in the sub-main panels or the breaker of the branch circuits in the main panels.
It has a higher short circuit capacity than MCB.


3- Air Circuit Breaker or ACB:
Usually, it will be the main breaker in the main panels or MDB.
It has higher short-circuit capacity than MCB & MCCB

Shunt Trip Coil

A shunt trip coil is an optional accessory in a circuit breaker that mechanically trips the breaker when power is applied to the shunt trip terminals.

The power for the shunt trip does not come from within the breaker, so it must be supplied from an external source.

Its most common application is when we need to control switching off the power of a panel by a feedback signal from the BMS system.

In today's highly competitive job market, professional development has become essential for success.

As the world continues to evolve, it is vital for engineers to stay up-to-date with new technology and software.

One such software that has gained immense popularity in the construction industry is Revit.

Revit is known as a Building Information Modeling (BIM) software; it's being used extensively by architects, engineers, and construction professionals.

Grease Interceptor πŸ‘Œ

A grease interceptor is an in-ground or suspended tank that is designated to limit the amount of FOG (fat oil and grease) and solids entering the sanitary sewer system.

Interceptors hold FOG until they can be removed and disposed of by recycling or rendering companies(Manual cleaning).

Interceptors are more effective when the grease traps are inspected weekly and periodically.

Types of Traps in Western Water Closets 🚽

In order to form a seal and prevent (trap) unwanted gasses from escaping from the sewerage, the trap retains some water. πŸ’¨πŸ’§

For an S-Trap toilet, the soil drainage pipe exits the toilet through the floor.

While in a P-Trap, the soil drainage pipe exits through the wall.

The easiest way to remember this is by remembering the direction of drainage water flow, as shown in the attached photo of this post.

Importance of Coloring Embedded Conduits and outlets in Concrete Slabs

It’s preferable before installing embedded conduits and outlets in the concrete slab to use a pre-colored conduits and outlets, but if they are not available, you can use spray paint to identify each system’s outlets and conduits.

This will help the electrician to identify each outlet for which system, Ex: Lighting - power - Fire Alarm - CCTV...etc.

Because if all conduits and outlets with the same color (Ex: White), so it will take time from your team to differentiate between each system’s conduits & outlets, which increase the cost of manpower and time.

Important Note about MEP Works in Toilets 🚽

One important note to be considered for MEP works in toilets is to complete the chipping of MEP services before applying waterproofing to the toilet’s floor.

The note is already explained in the attached photo.

Types of Lighting Lamps

Lighting lamps come in many different types and styles, each designed to serve a specific purpose.

As per their principle of Operation, we can divide them into three categories:

A- Filament Lamp.
B- Gas Discharge Lamp.
C- LED Lamp.

Each type of them can be divided into sub-categories.

πŸ”₯πŸ“š FACTUAL DATA ALERT!πŸ“šπŸ”₯

Did you know using an electrode dryer before welding black steel pipes is crucial?

Here's why:

πŸ” Moisture can negatively affect your welding.

πŸ’¦ Drying Low Hydrogen electrodes before use ensures high-quality welds.

πŸ’» The primary purpose of the electrode Dryer is to keep the electrodes dry and prevent moisture absorption.

πŸ“ The composition specifications of solid welding electrode wires and rods are vital.

πŸ‘· Pre-preparation of pipes before welding improves the quality of the weld seam.

πŸ’ͺ Using a medium-coated electrode is perfect for mild steel and can help avoid undercut and excessive convex fillet.

Remember, welding specification of carbon and alloy steel piping is essential. 😎

What is the reason for painting this metal duct red?

The photo shows a black steel duct that can be used in different applications like kitchen hoods.

As this duct will not be insulated, we paint the outer surface of black steel ducts with red oxide coating.

This coating acts as a preparatory or protective coating that prevents rust formation on the ferrous metal surfaces exposed to humidity and air.

Understanding the Data of MCCB

MCCB is an abbreviation for Modled Case Circuit Breaker.

MCCB can be used as the main breaker of a panel, the breaker of a branch circuit, or both in the same panel.

There is a lot of information available on the body of its enclosure.

So, we summarized this information, as you can see in this photo.
