How many air switches are in the distribution box for the 20′ expansion box and how many P’s are in it?

feekergroup — Fri, 27 Jun 2025 09:03:26 +0000

For information on the number of air switches (air openers) and the number of poles (P-number) in the distribution box of a 20′ expansion box, a comprehensive distribution system design and common industrial configurations, refer to the following information:

I. Number of openings

This kind of distribution box is usually configured with 6-10 circuits, the specific number should be combined with the actual demand for electricity:

1. main switch: 1 (mandatory)

2. partition control:
● Lighting circuit: at least 1
● Socket circuits: 2-4 circuits (ordinary sockets, independent circuits for high power equipment)
● Equipment-specific circuits: such as air conditioners, motors, etc. added as needed.

3. Extended reservation: some designs will reserve 1-2 spare circuits.

II. The number of open poles (P number)

Selected according to functional requirements:

1. Main switch: 2P or 4P air switch is required
● Double-pole (2P): cut off the fire wire and zero wire at the same time, applicable to single-phase power system
● Four-pole (4P): for three-phase electrical system (such as 380V industrial equipment), including zero wire control

2. Branch circuit:
● Lighting/ordinary sockets: mostly use 1P or 1P+N openers (only control the fire wire, zero wire through)

● High-power equipment (air conditioners, motors, etc.): give priority to 2P openers, to ensure complete disconnection

● Humid areas (such as outdoor equipment): need to be paired with a Leakage protector (2P leakage protection)

III. Configuration examples

Typical scheme (single-phase electrical system):

Circuit type	Number of openings	Polarity selection
Main switch	1	2P
Lighting circuit	1	1P
General outlet	2	1P+N
Air conditioner/equipment only	2	2P
Leakage protection circuit	1	2P Leakage protection
Total	7 pcs.	—

⚠️ Actual configuration to be adjusted according to equipment power, voltage type (single phase/three phase) and safety codes. It is recommended to consult the technical drawings of the box or consult the manufacturer to confirm the specific parameters.
