Terms to know

Ah (amp-hour)

A measure of electric charge: one amp flowing for one hour is one amp-hour. Compare battery energy at the same voltage, or convert nominal capacity to watt-hours with…

AWG

American Wire Gauge, a conductor-size system in which a larger numbered gauge generally means a smaller conductor. Cable selection also depends on insulation, installation conditions, length, and current.

BMS

Battery management system. It monitors battery conditions and may restrict charging or discharging when limits are reached; it does not replace correctly selected external wiring protection.

Breaker

A resettable device that opens a circuit under specified fault conditions. A breaker must be rated for the AC or DC circuit in which it is used.

Busbar

A conductive bar used as a common connection point for several circuits. Its rating and protective cover are part of the system design.

Change order

A documented change to an agreed project. Confirm its effect on parts, labor, price, and schedule before the extra work begins.

Crimp

A connection made by compressing a terminal around a conductor with a suitable tool. The terminal, cable size, die, and tool must be compatible.

Disconnect switch

A switch intended to isolate part of an electrical system. Whether it may interrupt a live load depends on its rating and the installation design.

Fuse

A replaceable protective device that opens a circuit when its specified overcurrent conditions are reached. Selection includes current, voltage, time-current behavior, and interrupt rating.

Handoff documentation

The records supplied when an installation is completed, such as diagrams, equipment details, settings, test results, and operating instructions.

Labor warranty

The installer’s stated coverage for workmanship. Ask what work is covered, for how long, and how a claim is handled; product coverage may be separate.

Liability insurance

Insurance a business may carry for certain claims connected to its work. Ask the business for current evidence of coverage relevant to your project.
