The manufacturer of Small Power Distribution Unit (SPDU) shall follow certain technical requirements during production to ensure the performance, quality and technology of Small Power Distribution Unit (SPDU). The following is a brief introduction by the Small Power Distribution Unit (SPDU) factory:

1. Schneider, ABB and Mueller products can be used for the main switch and separation in the Small Power Distribution Unit (SPDU), and electromagnetic products can be used for the leakage switch in the household Small Power Distribution Unit (SPDU); The thickness of the small Small Power Distribution Unit (SPDU) shall not be less than 1.5mm, and the color shall be determined separately. There shall be enough space for wiring in the box. The independent zero line and ground wire terminals shall be sent to Party A and the supervising engineer for approval before production. Before surface treatment, the samples shall be inspected by Party A and the supervising engineer on site.

2. The main switch to the sub switch of the Small Power Distribution Unit (SPDU) manufacturer shall be connected with copper bar (no bare conductor) and meet the acceptance requirements of the specification, and shall not be connected with copper wire; The cross section of outgoing wire of main switch shall not be less than that of incoming wire; Circuit labels shall be typed with plastic strips and fixed firmly.

The main purpose of designing the circuit of the Small Power Distribution Unit (SPDU) is to make the inside of the Small Power Distribution Unit (SPDU) look clean and tidy, and to improve the safety factor.

When transporting the Small Power Distribution Unit (SPDU), we need to protect it. In the outer layer, we can use the wooden box for packaging. In the gap between the wooden box and the box, we can use foam board to fill and fix it firmly, so as to ensure that the Small Power Distribution Unit (SPDU) will not have a large displacement during transportation
