以家庭为例，所用的电器有感性负载也有阻性负载，因此计算额定电流是P＝UI和P＝UIcosΦ。假设家里的电器总功率为10KW，那么计算得到的大电流I为56A。众所周知，家里的电器也不可能同时工作，因此要给予一个同时系数0.6-0.8。因此系数取0.8，计算得到45A。所以家里的总电源线可以用6平方毫米铜芯BV系列的电线电缆。实际使用过程，电线电缆的工作环境温度、电线电缆敷设方式、穿线管内穿线数等都是对电线电缆截面选择有影响的。

先说一下我对洗澡时触电所持有的观点：不建议断电洗澡——如今的电热水器早已不同于当年，如今的电热水器早就具备了插电洗澡的能力。这个时候，我们要考虑的是怎样更安全的插电洗澡，而不是永远考虑下下策——断电洗澡。就好像汽车必须研发出更安全、更可靠的安全系统，而不能单纯的依靠驾驶员开慢一点。电热水器从配电箱开始到电热水器结束，共有四重保护：配电箱内漏电保护开关，热水器自身的漏电保护器，地线的接地保护，卫生间的局部等电位。
