If you smell gas nowLeave the building without using switches, flames, or phones indoors. From outside, call 911 if there is immediate danger and call your gas utility. Contact a private-side contractor only after the area is declared safe.
The short answer
Sizing depends on generator input, delivery pressure, run length, meter capacity, and the appliances expected to operate during an outage. The electrical installer, generator supplier, utility, and gas contractor should agree on responsibilities before trenching.
What matters in this situation
An appliance hookup is only as safe and reliable as the piping that feeds it. The existing branch, shutoff, connector, venting responsibilities, and combined gas demand all need to be understood before connection.
Details that help define the next step
- Generator model and fuel input
- Proposed location and route
- Existing meter capacity
- Expected simultaneous appliance use
These details help establish scope; they do not replace an emergency response, onsite inspection, utility decision, permit requirement, or manufacturer instruction.
How a careful service process is organized
- Start by documenting generator model and fuel input and proposed location and route.
- Confirm existing meter capacity and expected simultaneous appliance use before the scope is finalized.
- Have generator specification sheet and site plan and clearance location ready for the onsite team or authority.
- Use the findings to define the appropriate gas appliance hookup scope, required testing, and any next authority or trade.
What to have ready when requesting service
- Generator specification sheet
- Site plan and clearance location
- Electrical-contractor contact
- Utility correspondence
What not to do
Do not place or trench for the generator before the gas route and capacity are confirmed. Keep relevant tags, notices, equipment information, and safely obtained photos available for the people handling this specific situation.
