Home electrical distribution box does not have a circuit breaker
A home electrical panel might not have a main breaker because it's a split-bus panel (common in 1950s-1970s homes), has a main disconnect located elsewhere, or uses a rule of six design 1 with multiple disconnect switches instead of a single main breaker. Looking at your electrical panel and can't find the main breaker? This common issue leaves many homeowners confused and worried about safety. The main disconnect is usually 200 amps but can sometimes be as low as 100 amps. The main disconnect is a safety device that lets you shut off all power to a house. A main breaker, or service disconnect, is a single switch designed to interrupt all electrical power flowing from the utility company into a home's electrical panel. Any subpanels are only required to have a disconnect breaker upstream in the main.

Does the distribution box only have one circuit
An electrical power distribution box, also called a distribution board or breaker panel, serves as the hub where incoming power is split into multiple circuits. With a distribution box, circuits won't be overloaded. Circuits, of course, can only support so much electrical power. Distribution boxes work by distributing electrical power while simultaneously protecting. A distribution board (also known as panelboard, circuit breaker panel, breaker panel, circuit breaker, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit. A distribution board is a fixed electrical panel that divides power into circuits with protection; a distribution box is more compact or portable, used for junctions or temporary setups. It receives power from the main electrical supply and divides it into separate circuits, each. A electrical distribution box is essential for managing and controlling electrical power flow in any system, preventing overloads and short circuits, which are vital for safety and reliability.
