What size thermal relay protector should I pair with a 750W circuit
Here's a simplified checklist when deciding what size overload relay you need: Confirm the motor's FLA and service factor. With this tool, you can quickly determine: Full Load Current (FLC) – the actual current your motor will draw at rated load. Use Motor Circuit Protection Tables to verify compatibility between cable size, breaker size, and relay setting. If your motor is running in a high-temperature environment, derate the overload relay setting. Motors. Overload relays protect motors from overheating and excessive current by interrupting the circuit when abnormal load conditions occur. Kent Electrical Supply provides thermal and electronic overload. NEC Article 430, Part III provides guidelines for sizing overload protection devices such as, overload relays, fuses and circuit breakers for motor branch circuit conductors against excessive heating caused by overload currents.

Does the small busbar indicate the positive or negative terminal
The positive busbar connects to the battery's positive terminal, and the negative busbar to its negative terminal. They are called the buses, also referred to as rails, and are typically used to supply electrical power to your circuit when you connect them to a battery pack or other external power supply. In DC systems, such as those found in RVs, boats, or solar power setups, busbars organize complex wiring into a clean, orderly arrangement. It serves as a central point where different wires, cables, and components can be attached to a single system. Bus bars are typically made from materials with excellent electrical.
