Standard Operating Procedure for De-energizing a Low-Voltage Electrical Panel.
Purpose:
This Standard Operating Procedure (SOP) outlines the proper and safe procedures for de-energizing a low-voltage electrical panel in order to ensure safety and prevent accidents during electrical maintenance or repairs.
Scope:
This SOP applies to all authorized electrical personnel who are responsible for working on or around electrical panels.
Safety Precautions:
Always wear appropriate personal protective equipment (PPE), including insulated gloves, safety glasses, a hard hat, and flame-resistant clothing.
Ensure that the area around the electrical panel is clear of any obstacles and potential tripping hazards.
Have proper lockout/tagout procedures in place to prevent accidental energization of the panel during maintenance.
Never attempt to work on a live electrical panel.
Procedure:
1. Identify the Panel: Locate the electrical panel that needs to be de-energized. Make sure the panel is properly labeled and identified.
2. Confirm the Power Source: Determine the power source for the panel. This can be a circuit breaker or fuse.
3. Turn Off the Circuit Breaker or Fuse: Locate the appropriate circuit breaker or fuse that supplies power to the panel. Turn off the breaker or remove the fuse.
4. Verify De-energization: Use a non-contact voltage tester to verify that the panel is de-energized. Test all phases of the panel to ensure that there is no residual voltage present.
5. Lockout/Tagout: Place a lockout device on the circuit breaker or fuse and attach a tag indicating that the panel is de-energized and should not be energized.
6. Confirm De-energization: Repeat step 4 to confirm that the panel is still de-energized after the
lockout/tagout procedure.
7. Proceed with Maintenance: Once the panel is de-energized and verified safe, proceed with the necessary maintenance or repair work.
Emergency Shutdown:
In the event of an emergency, follow these steps to de-energize the electrical panel immediately:
1. Trip the Main Breaker: Locate the main breaker that supplies power to the electrical panel. Trip the breaker to cut off all power to the panel.
2. Lockout/Tagout: Place a lockout device on the main breaker and attach a tag indicating that the panel is de-energized and should not be energized.
3. Evacuate the Area: Clear the area around the electrical panel and evacuate all personnel to a safe location.
Contacting Emergency Services:
If an electrical emergency occurs, contact emergency services immediately by dialing 911 or the appropriate emergency number for your location.

低压电柜断电正确流程。

目的：
此标准操作规程（SOP）概述了断开低压电柜的方法和步骤。

遵
循此操作规程可以确保安全，防止在电器维护或修理期间发生事故。

范围：
此 SOP 适用于负责在电气面板或周围工作的授权电工。

安全预防措施：
始终穿戴适当的个人防护装备（PPE），包括绝缘手套、安全
眼镜、安全帽和阻燃服装。

确保电气面板周围区域没有障碍物和可能绊倒的危险。

制定适当的锁定/挂牌程序，以防止在维护期间意外给面板通
电。

切勿尝试操作带电电气面板。

程序：
1. 识别面板，找到需要断电的电气面板。

确保面板贴有标签并正确标识。

2. 确认电源，确定面板的电源。

可以是断路器或保险丝。

3. 关闭断路器或拔下保险丝，找到向面板供电的断路器或保险丝。

关闭断路器或拔下保险丝。

4. 验证断电，使用非接触式电压测试仪验证面板已断电。

测试面板的所有相位，以确保没有残余电压。

5. 锁定/挂牌，在断路器或保险丝上放置锁定装置，并附加一个标签，表明面板已断电，不得通电。

6. 确认断电，在锁定/挂牌程序后，重复步骤 4 以确认面板仍处于断电状态。

7. 继续维护，在使面板断电并验证安全后，继续进行必要的维
护或维修工作。

紧急关闭：
在紧急情况下，请按照以下步骤立即切断电气面板的电源：
1. 跳闸主断路器，找到向电气面板供电的主断路器。

跳闸断路
器切断所有通往面板的电源。

2. 锁定/挂牌，在主断路器上放置锁定装置，并附加一个标签，表明面板已断电，不得通电。

3. 疏散区域，清除电气面板周围的区域，并将所有人员疏散到
安全的地方。

联系紧急服务：
如果发生电气紧急情况，请立即拨打 911 或您所在地区的紧急
电话联系紧急服务。
