Kari,
As long as no electrical life support equipment is required, then a Type 3 system is acceptable. If any electrical life support
equipment is required you would need to provide a Type 1 system per NFPA 99 14.3.4.2.1.
If in fact it is determined that all that is required is the Type 3 system, then NFPA 99 4.6.1.1 requires that generators conform to
requirements of 4.4.1.1
NFPA 99 and NFPA 101 do not specify fuel capacity or run time for generators.
NFPA 70 Section 700.12(B)(2) does require a minimum fuel supply of 2 hours for legally required standby emergency generators.
You may also want to contact HFS as they may have additional licensing requirements that may apply.
Please call me to discuss the type of system you are proposing to install. Based on the plans we have on file it appears that a Type
1 system had been planned.

Good afternoon Kevin,
We have a project in Oshkosh called The Renaissance Center. It has 11,700 square of Practice /Clinic space and 12,500
square feet of Ambulatory Surgery Center space. The projects address is 2400 Witzel Ave.
The specified Generator is 250 KW diesel with a sub base fuel tank
We would like to verify our assumption regarding required run -time for the generator i.e. this determines the size of the fuel
tank). We would like to confirm that we had interpreted the codes correctly.
This facility is an Ambulatory Heath Care under NFPA 101 Chapter 3.3.134.1. Under 20.2.9.2, an essential electrical system
was provided in accordance with NFPA 99 (Standard for Health Care Facilities).
From NFPA 99 Chapter 14 Other Health Care Facilities 14.3.4.2 The essential electrical distribution system shall
conform to type 3 system as described in chapter 4
From Chapter 4 (4.4.1.72) Type 3 essential electrical system power sources shall be classified as Type 10, Class X,
generator sets per NFPA 110, Standard for emergency and Standby power systems.
Class X defines the required run time for this generator
NPPA 110 Chapter 4 Classifications of emergency power supply systems (EPSSs).
Table 4.1(a) Classifications of EPSSs Class X Other time, in hours as required by the application code, or user. We
have assumed that the life safety code for emergency lighting of 1 1/2 hours is the required run time, the owner has indicated
that no procedure preformed at the facility would last longer than one hour.
Would it be your opinion that if the generator ran for at least 1 1/2 hours that the code is satisfied?
Kind regards,

Kari,
As long as no electrical life support equipment is required, then a Type 3 system is acceptable. If any electrical life support
equipment is required you would need to provide a Type 1 system per NFPA 99 - 14.3.4.2.1.
If in fact it is determined that all that is required is the Type 3 system, then NFPA 99 -4.6.1.1 requires that generators conform to
requirements of 4.4.1.1
NFPA 99 and NFPA 101 do not specify fuel capacity or run time for generators.
NFPA 70 Section 700.12(B)(2) does require a minimum fuel supply of 2 hours for legally required standby emergency generators.
You may also want to contact HFS as they may have additional licensing requirements that may apply.
Please call me to discuss the type of system you are proposing to install. Based on the plans we have on file it appears that a Type
1 system had been planned.

Good aftemoon Kevin,
We have a project in Oshkosh called The Renaissance Center. It has 11,700 square of Practice/Clinic space and 12,500
square feet of Ambulatory Surgery Center space. The projects address is 2400 Witzel Ave.
The specified Generator is 250 KW diesel with a sub base fuel tank
We would like to verify our assumption regarding required run-time for the generator ( i.e. this determines the size of the fuel
tank). We would like to confirm that we had interpreted the codes correctly.
This facility is an Ambulatory Heath Care under NFPA 101 - Chapter 3.3.134.1. Under 20.2.9.2, an essential electrical system
was provided in accordance with NFPA 99 (Standard for Health Care Facilities).
From NFPA 99 - Chapter 14 Other Health Care Facilities 14.3.4.2 - "The essential electrical distribution system shall

NPPA 110 - Chapter 4 - Classifications of emergency power supply systems (EPSSs).
Table 4.1 (a) Classifications of EPSSs - Class X = Other time, in hours as required by the application code, or user. We
have assumed that the life safety code for emergency lighting of 1 1/2 hours is the required run time, the owner has indicated
that no procedure preformed at the facility would last longer than one hour.
Would it be your opinion that if the generator r~n for at least 1 1/2 hours that the code is satisfied?
Kind regards,
