Electric meter or distribution box

A meter box measures electricity usage, while a distribution box distributes and protects electrical power across circuits.

Meter Box

A meter box is an enclosure designed to house the electricity meter and related service connections. It serves as the formal interface between the utility power supply and the consumer's internal electrical system, typically installed at the point of entry or on an exterior wall for easy access. Its main functions include measuring energy consumption for billing, protecting the meter from weather and tampering, and allowing authorized utility access for inspection and maintenance.

Meter boxes may also include anti-theft devices depending on local requirements.

Distribution Box

A distribution box (also called a distribution board or breaker panel) receives power from the main supply and distributes it to multiple branch circuits within a building. It is usually installed indoors in service rooms or accessible locations. The distribution box houses protective devices such as MCBs (Miniature Circuit Breakers), RCCBs (Residual Current Circuit Breakers), or RCBOs to safeguard circuits against overloads, short circuits, and leakage currents.

Its primary purpose is to control and manage electricity flow to lighting, appliances, and equipment while ensuring safety.

Key Differences

Function: Meter box measures electricity; distribution box distributes and protects circuits. Location: Meter box is often outside; distribution box is usually inside. Components: Meter box contains the meter; distribution box contains breakers, fuses, and protective devices.

Purpose: Meter box ensures accurate billing and utility monitoring; distribution box ensures safe and controlled power distribution.

Types of Distribution Boxes

Distribution boxes can vary based on application: Main Distribution Board (MDB): Central hub for distributing electricity to multiple sections. Sub Distribution Board (SDB): Transfers power to specific areas like garages or parking lots. Meter Panel: Combines metering and distribution functions for residential or commercial use.

Understanding the distinction between these two enclosures is essential for safe electrical installation, maintenance, and compliance with regulations. Proper selection and placement ensure both accurate energy measurement and reliable circuit protection.
