FAQs
What size terminal block do I need?
Match the block to your cable size and current demand – for example, 16mm² blocks for sub-mains, or 100A blocks for heavy-duty feeds.
Are pluggable terminal blocks worth it?
Yes – they save time in modular or repeatable installs where circuits need to be disconnected and reconnected regularly.
Can I use plastic blanks in a metal enclosure?
Yes – both metal and plastic blanks are compliant, but metal blanks are preferred for fire resistance where required by regs.
