为了安全地用电力工作,您必须尊重其权力。如果您了解其性质,并注意本指南中的安全警告 - 特别是关闭电源和测试voltage testerto make sure power is off—you can work on electrical systems safely. The cardinal rule of home-improvement projects, which goes double for electrical work, is this: Know your limitations.
安全AlertTest the tester first and last. No matter what kind ofelectrical testeryou’re using, test it first on a circuit that you know is hot to make sure the tester is working properly, and do the same after you’ve done the testing. Most testers run on batteries, and those batteries could die after your pre-test check and before the voltage test. The post-test check will catch that. |
除非您以前的经验做电气工作并对您的技能感到充满信心,否则您应该将某些项目留给专业人士。在服务面板内工作或甚至拆除其盖子可能是特别危险的。在大多数面板中,即使在断路器设置为OFF位置之后,主断路器周围的主断路器也存在一个区域。此外,一些较旧的面板没有主断路器,它需要经验来了解面板的布局。

永远不要尝试删除通电服务面板或通电子盖的封面或工作。致电持牌电工而不是危险伤害。
The safety alerts and safe working practices explained in this chapter will go far to protect you, but the best protection is knowledge. We strongly recommend that readers visit theOSHA / Niosh网站电气安全as well.
Always wear appropriate safety gear, including rubber-soled shoes, sturdy gloves, safety glasses, and a respirator or dust mask when sawing or drilling overhead. Remember that 120 volts can kill or cause serious shock, so learn and use safe work practices; your life depends on it.
