What gauge wire to use when adding a start capacitor and relay?
Adding an OEM start capacitor and relay on an old RHEEM RAKA 2.5 ton that didn''t have one. Ordered without wiring harness and not 100% sure what gauge wire I should use to wire it up. It looks like most of the aftermarket hard start kits use around 16 to 18 gauge wire. Planning on using stranded 12 AWG rated for 600v 105 degrees Celsius.
What is the required capacitor value for a 2hp 1-phase induction motor ...
Thumb Rule: One common thumb rule for calculating the capacity of a capacitor is to use 50 microfarads for every 1 kilowatt (KW) of power. For a 2hp motor, which is approximately 1.5 KW, the capacitor value would be around 75 microfarads . Motor Label: The motor label usually provides information about the required capacitor value.
Are too high capacitance capacitors "bad" for the circuit?
$begingroup$ @mkeith I realize that there''s no universal best capacitor. I was just wondering what behavior a too big one actually displays and/or what effect it has on the current. The "know what you are doing" can only be achieved by learning and knowing at least some of the behaviors I can understand the topic easier without DIY capacitor explosions and …
Motor starting capacitor | Applications | Capacitor Guide
Motor start and motor run capacitors Start capacitors. Motor start capacitors are used during the motor startup phase and are disconnected from the circuit once the rotor reaches a predetermined speed, which is usually about 75% of the maximum speed for that motor type. These capacitors usually have capacitance values of over 70 µF.

Purpose of the diode and capacitor in this motor circuit
A small capacitor across the motor will reduce the speed of the possibly fast voltage transitions, which causes less radiation and limits the dV/dt the transistor is subjected to. 100 nF is excessive for this, and will prevent efficient operation at all but low PWM frequencies. I''d use 100 pF or so, perhaps to up 1 nF.
