Frequently Asked Questions
What is a main earth terminal block used for? It gives a single bonding point in a panel or enclosure, where the incoming earth conductor and the protective earth conductors of each circuit are connected together.
What’s the difference between the 5, 7 and 10-way versions? The number of additional earthing points (3, 5 or 8) alongside the 2 larger main earth terminals pick based on how many circuits need grounding.
What cable range does this accept? 2 x larger main earth terminals for 6~16mm cable, plus 3/5/8 additional 6.5x9mm earthing points depending on model.
Can this be used with unterminated cables? Yes suitable for both terminated (ring/spade) and unterminated (bare or ferruled) cables.
