Please replacement <b>Item# 45330</b>. Generac Guardian Air-Cooled Standby Generator — 14kW (LP)/13kW (NG), 100 Amp Transfer Switch, Model# 6240

The gas line material and size should be determined by a Generac certified installer or a certified plumber to meet your local and state codes. The generator will come with a flexible fuel line which measures one foot in length and should be utilized between the generator and the installed fuel line to prevent the generator vibrations from damaging either the internal regulator or the rigid pipeline. The line size should be on the volume and pressure required. The volume and pressure required for the 14kW unit, model number 6240, utilizing natural gas is 140,000 BTU/hr with 3.5-7” water column. Furthermore, the loads required in a house will vary, and are determined by the items you deem necessary to run in an outage situation. To properly determine the correct generator for your needs, we recommend working with your local certified dealer or local certified electrician, as they will be able to determine the correct size generator to meet your needs.

If you are utilizing a Generac brand EZ-Switch transfer switch, the total amperage of the circuit breakers cannot be increased, but multiple smaller breakers can be removed to accommodate a larger breaker, and a larger breaker can be removed to accommodate a smaller breaker. For example, if another 20 amp 120 volt breaker were needed, either two of the 15 amp 120 volt breakers could be removed and have that 20 amp breaker installed, or a 30 amp breaker can be removed and have that 20 amp breaker installed. A single 15 amp 120 volt breaker cannot be replaced with a 20 amp 120 volt breaker as that is increasing the total amperage. We recommend speaking with your inspector for approval to modify the switch, as modifying the switch from the factory setting can void the UL listing. Your local codes may also require the use of arc fault breakers when replacing the already existing breakers.

Our 14kW automatic standby units are CARB compliant. Local codes will dictate whether a permit is necessary for installation of a generator.

The Guardian series automatic standby units are designed as a back-up to utility power only. Utilizing the unit in place of utility – prime power – will void the unit’s warranty.

On this Generac GUARDIAN Series Air-Cooled Automatic Standby Generator, the brand name of the circuit breakers used in the transfer switch are Siemans.

If the items that will be connected to the 100 amp automatic transfer switch that is included require less than the 100 amps to operate, then the 100 amp switch is all that is needed.

You would need to determine all the appliances you will need to run during a power outage. Then add up the wattage requirements to be sure to get the right size generator. Northern would typically recommend consulting with your local electrician to properly size your home.
