When installing CSST in a structure, what bonding requirement must be met to comply with BGE and code requirements?
Answer: CSST must be bonded to the electrical grounding system to prevent lightning strike damage
CSST must be bonded to the building's electrical grounding system because lightning-induced electrical surges can arc through CSST and cause leaks or fires.
Which valve type is required as the main shutoff on a new gas service installation entering a residential building?
Answer: Ball valve or plug valve listed for gas service
A ball valve or plug valve listed for gas service is required as the main shutoff because it provides a full-bore, quarter-turn shutoff that is reliable and easy to operate.
When installing gas piping through a foundation wall, what is required at the penetration point?
Answer: A sleeve larger than the pipe must be installed to allow for movement and sealing
A sleeve larger than the pipe must be installed at foundation penetrations to allow for building settlement and to prevent pipe stress while the annular space is sealed.
What pressure test is typically used to verify the integrity of new gas piping before placing it in service?
Answer: An air or nitrogen pressure test at 1.5 times the maximum allowable operating pressure
New gas piping must be pressure-tested with air or inert gas (not gas) at 1.5 times the MAOP to verify integrity before being placed in service.
When installing gas piping near electrical wiring, what minimum separation should be maintained?
Answer: 3 inches separation
Gas piping should maintain a minimum 3-inch separation from electrical wiring to prevent arcing and reduce fire risk.
Which of the following is the correct method for joining polyethylene gas pipe?
Answer: Butt fusion, socket fusion, or electrofusion fittings
Polyethylene gas pipe must be joined using heat fusion methods (butt, socket, or electrofusion) or mechanical fittings specifically listed for gas service PE pipe.
When must a gas service line be electrically isolated from the customer's interior piping system?
Answer: When the service line is cathodically protected, an isolating fitting must be installed at the meter
An isolating fitting (dielectric union) is installed at the meter to electrically separate the cathodically protected service line from the unprotected interior piping.
