Hospital Isolated Power Panels (IPP) — NFPA 99 Compliant Solutions Across Saudi Arabia
Life-critical power protection for operating rooms, ICUs & wet procedure locations
What Is an Isolated Power Panel?
An isolated power panel (IPP) is a hospital-grade electrical system used in operating rooms and other "wet procedure locations" — one of the recognized electrical-protection methods under NFPA 99/NFPA 70, alongside GFCI protection. Whether it's required for a specific room depends on the facility's risk assessment, the applicable code edition and the authority having jurisdiction. Instead of grounding the electrical system directly, an IPP electrically isolates the power supply so that a single ground fault does not trip the breaker or interrupt power — critical equipment stays running while the fault is detected and alarmed.
This matters because in an operating room, an unexpected power interruption during a procedure is not just inconvenient — it can be dangerous. A line isolation monitor (LIM) continuously watches for faults and alerts staff immediately, giving the surgical team time to respond safely without the system cutting power outright.
You may also see this equipment called an isolated power system (IPS) or isolated power supply — different manufacturers and regions use slightly different names for the same underlying equipment: an isolation transformer paired with a line isolation monitor, feeding an ungrounded circuit to a wet procedure location. Whichever term appears on your tender or specification, the NFPA 99 requirements and equipment function are identical to an IPP.
Isolated Power Panel — Typical Technical Parameters
| Panel Capacity | 3 kVA – 10 kVA, sized to connected medical equipment load |
| Line Isolation Monitor (LIM) Alarm Threshold | 5 mA total hazard current, per NFPA 99 |
| Isolation Transformer | Medical-grade isolation transformer feeding an ungrounded circuit |
| Line Voltage | Matched to facility system — commonly single-phase 120V or 230V |
| Governing Standards | NFPA 99, NFPA 70 (NEC Article 517), SASO |

Hospital Application Scenarios
IPP Maintenance Plans
One-Time Maintenance
A single scheduled visit — full panel inspection, line isolation monitor calibration check, and functional testing. Ideal ahead of a compliance audit or facility inspection.
Preventive Maintenance
Scheduled recurring visits to test alarms, calibrate the line isolation monitor, and catch degradation before it becomes a fault — keeps your system audit-ready year-round.
Corrective Maintenance
Rapid-response repair when a fault, alarm, or component failure occurs — our technicians diagnose and fix the issue to restore full compliance and uptime.

Frequently Asked Questions
What size isolated power panel do I need for an operating room?
Sizing depends on the connected medical equipment load in that room, not a fixed number — a typical OR panel falls somewhere in the 3–10 kVA range. We run a load assessment against your actual equipment schedule before specifying a panel, rather than defaulting to a standard size.
How is an isolated power panel different from a UPS?
They solve different problems. An IPP protects against a ground fault interrupting power mid-procedure — it isolates the circuit and alarms on a fault instead of tripping the breaker. A UPS protects against a utility outage by switching to battery power. An operating room typically needs both: the IPP for ground-fault safety, and a UPS upstream or downstream of it for outage backup.
What is an isolated power panel (IPP) and why do hospitals need one?
An isolated power panel is a hospital-grade electrical system used in operating rooms and other wet procedure locations — one of the recognized electrical-protection methods under NFPA 99/NFPA 70, alongside GFCI protection, with the specific requirement for a given room depending on the facility's risk assessment and the authority having jurisdiction. It electrically isolates the power supply so a single ground fault doesn't interrupt power to life-critical equipment — a line isolation monitor alerts staff to the fault instead of cutting power outright.
Which IPP brands does Black Arrow supply?
We supply Bender isolated power panels and PG LifeLink IPP panels. Our designs are also compatible with Schneider Electric-style isolated power system specifications where a project calls for it.
What standards do your isolated power panels comply with?
Our IPP installations are engineered to NFPA 99, NFPA 70, and applicable SASO requirements for installed electrical equipment in Saudi Arabia.
