Power Distribution: What You Need to Know

Power distribution equipment, also known as electrical panels or breaker assemblies, is essential for safely routing electricity through residential, commercial, and industrial systems. These systems operate across a wide ampere range from 15A to 225A, where amperes (amps) measure the amount of electrical current flowing through a circuit. Selecting the correct amp rating ensures safe and efficient power delivery tailored to the system's load requirements.

Type:

  • Breaker Box Parts: These include internal accessories and mounting hardware used to assemble or repair existing panels. They ensure smooth operation and compliance with safety standards.
  • Breaker Boxes: Serve as the central hub for distributing electrical power within a structure. They house breakers and protect circuits from overloads or short circuits.
  • Circuit Breakers: Automatically interrupt power flow during overloads or faults. These critical components protect both wiring and connected appliances from damage.
  • Disconnects: Provide a means to manually shut off power to specific areas or systems. Ideal for servicing, maintenance, or emergency cutoffs.
  • Meter Main Combos: Combine the functions of a main breaker and utility meter socket in one enclosure. Frequently used in new residential construction for space-saving efficiency.
  • RV Electrical Panels: Custom-built to handle mobile power demands, RV panels safely distribute electricity in recreational vehicles. They often include multiple outlets and surge protection.
  • Spa Panels: Specifically designed for spa and hot tub installations, these panels ensure safe, code-compliant power delivery to water-based systems.

Ampere:

  • 15A – 30A: Typically used for lighting circuits, small appliances, and individual residential outlets. These lower amperages are ideal for systems with minimal load demands and basic branch circuits.
  • 40A – 70A: Supports heavier residential needs such as electric ranges, dryers, and HVAC systems. Also common in spa panels and high-demand standalone units.
  • 100A – 125A: A standard for small to mid-sized homes, this range powers entire households efficiently. It balances capacity with affordability and is often used in main service panels.
  • 200A – 225A: Designed for large residential buildings or commercial setups. These higher-capacity systems support multiple sub-panels and extensive load distribution with increased reliability.
