lb Series - Ground Fault Circuit Breaker - 120/208/240 V AC

LB230-G – Product Description

🔌 What it is

The LB230-G is a 30-amp, 2-pole ground-fault (GFCI) circuit breaker used in residential and light commercial electrical panels to provide both overcurrent protection and shock protection on 240V circuits.

🧾 What the model code means

• LB → Leviton load center breaker series
• 230 → 30A, 2-pole breaker rating
• G → Ground-fault (GFCI protection)

⚡ What it does

This breaker:

• Protects 240V circuits (2-pole) from overloads and short circuits
• Detects ground faults (current leakage) and trips quickly to prevent shock
• Combines:
  • Standard thermal-magnetic protection (overload/short circuit)
  • GFCI protection (shock hazard prevention)

It monitors imbalance between hot conductors and trips if current is leaking to ground (like through a person or water path).

🏠 Typical uses

• Hot tubs and spas
• Outdoor HVAC or equipment circuits
• Pool pumps
• Well pumps
• Wet or damp-location equipment
• Certain EV charger or specialty 240V loads (when required by code)

🧠 Simple explanation

This is a 30-amp breaker for 240V circuits that also protects people from electric shock by shutting off power if it detects current leaking to ground.
