关于此计算器

How this is calculated

The tool lists how a hand-held appliance may be supplied. It reads regs 88, 89 and 89A of the Electricity (Safety) Regulations 2010. It points at the regulation. It does not rule on a site or a system.

  1. Situation. You pick where the appliance is used. The choices are anywhere, immersed or conductive surroundings, damp, outdoor or under construction, or a cramped space.
  2. Regulation. The tool picks reg 88(1) for any appliance, or reg 89 or 89A for the harder situations.
  3. Voltage to earth. It gives the maximum voltage to earth from reg 88(2). For an earthed source in some situations, it gives the lower figure from reg 89(2)(d).
  4. Paragraphs. It counts the connection methods or supply arrangements the regulation lists. It then names each one.
StepTable or clauseWhat it decides
Connection methodsreg 88(1)(a), (b) and (c)The ways to connect, as alternatives
Maximum voltagereg 88(2)The voltage to earth limit
Supply arrangementsreg 89(2) and reg 89AThe arrangements for the harder situations

Worked example

A hand-held appliance used outdoors or on a building site. The tool lists 7 supply arrangements under reg 89(2). The maximum voltage to earth is 250 V. For an earthed source it is 55 V.

Limits

  • The tool is a pointer. It is not a ruling and it is not advice.
  • The paragraphs of reg 88(1) are alternatives. They are not a cumulative set.
  • Reg 88(3), reg 89(3) and reg 89A(2) address offences. The tool holds none of that detail.
  • The tool read the regulations as at 15 January 2026. Check for a later version.
  • It does not check the cord length or the RCD. Use the site cord length and RCD selection tools.

问题

结果仅供设计参考。请依据现行标准核对。

本工具对手持器具报告什么？

它为所列的每一项注明对应条款：连接对应 reg 88(1)，对地最高 250 V 交流对应 reg 88(2)，场所情况对应 reg 89(1)、reg 89(2) 或 reg 89A(1)。AmpSize 仅指向参考条款，不对任何现场或系统作出裁定。

潮湿环境、户外或施工场所有哪些不同？

reg 89(2) 列出七种供电安排，而 reg 89(1) 和 reg 89A(1) 各列出三种。其中七种之一，即 reg 89(2)(d)，依据对地最高 55 V 交流的接地电源。各项措辞请阅读 reg 89(2)(a) 至 reg 89(2)(g)。

哪条法规涵盖狭小空间？

reg 89A(1) 涵盖狭小空间，reg 89(1) 涵盖浸没或导电环境。请阅读各条所设定的适用范围。两者各列三段，而 reg 89(2) 列七段。AmpSize 为三份列表中的每一项注明其所依据的段落。

为何 AmpSize 只报告一个电压数值？

这些法规中有两个 250 的数值，但依据不同。Reg 88(2) 规定对地交流电压为 250 V。Reg 89(1)(a)、reg 89(2)(a)、reg 89(2)(f) 和 reg 89A(1)(a) 依据导体之间的电压，AmpSize 未公布该依据下的数值，因此二者不会混淆。

本工具是对某项工程的裁定吗？

否。AmpSize 列出法规条款及款次，并报告其所含数据。它不评估任何现场、器具或工作，也不构成法律意见。reg 88(3)、reg 89(3) 和 reg 89A(2) 涉及违法行为，AmpSize 不包含这些细节。
