Some poles are three-pole breakers requiring three-phase power. In reality, these are two separate circuits joined to one button. A single-pole switch is assigned to one circuit while a double pole is assigned two circuits within the same button. Mostly, poles can either be single or double.
Breaker size helps electricians to decide the size of wires to use.Ī pole or a phase means the total separate circuits controlled by a switch. The smallest can be 2 amps while the largest can be 32 amps, 1000 amps, 5000 amps, or more.Ĭircuit breakers for lighting circuits are small but those that serve cookers, freezers, or water heaters are large because the appliances require more amperes/voltage. Circuits are made of wires of different sizes depending on the amount of power required.ĭepending on which equipment the breaker has served, some of them are big while others are small in terms of amperes. A circuit is simply a power connection from point A to point B through which electricity can flow. The numbering can be done according to the section the circuit serves. The circuits can be given any numerical digit but it must be unique to avoid confusion.
These could be apparatus, appliances, cables, conductors, insulators, motors, pumps, poles, fans, etc. The panel board will guide them by showing these details. When an electrician is new to a commercial site, the first thing they should request is the fillable panel schedule template that shows the details of panels and machine connections. The electrician should be keen to identify correctly which panel powers which equipment or machine. In a busy commercial site, there are usually a lot of panels meaning there are also a lot of schedules to deal with. It is different from an equipment schedule because the latter guides on the type of wiring and power are required for certain equipment in terms of ampacity, volts, or phase. A fillable panel schedule template can be created before connecting or after connecting circuits.Īn electrical panel schedule template is used as a guide to electricians when they need to identify which machine needs power. Power schedules provide accurate documentation and design for electrical machinery. It is a critical schedule used by electrical experts to design different projects and to determine how much power is needed for their installation and operation.Įlectrical engineers use a panel board schedule to assess overload issues and install the relevant safety systems. Electrical experts use an electrical panel schedule template to create a panel board schedule.
