Power connectors as used extensively within United Kingdom for mains-power connections up to 13 Amps. The range of connectors conforms to a format (and associated standards where applicable) adopted by UK standards authorities and relevent Electrical Industries and some are now compatible with international standards.
Among CASA's stocks there are some legacy products (no longer in current production) and some of these may only be used for maintenance purposes because they may no longer meet the current electrical regulations.
Note: Purchasers should always refer themselves to current regulations before deploying any mains-power electrical components.
