Henley block
Also known as Service connector block
A Henley block is a service connector block used in the meter and intake area to split or join meter-tail conductors, not proof that the supply is suitable for extra equipment.
A Henley block is trade shorthand for a service connector block used in the electricity meter or intake area to split or join large supply conductors such as meter tails. In home energy paperwork it may appear where solar PV, battery storage, EV charging or heat-pump work needs a separate isolator, consumer unit, load-management device or supply-capacity note. Product data may describe single-pole or double-pole connector blocks, 100 ampere ratings, multiple ways and conductor-size ranges, so the exact arrangement is product-specific.
