SP Assembly, IP20, 2 x 16A 110V, 1 x 16A 24V and 2 x 13A sockets, 2 kVA transformer

Purpose built, multi voltage Single Point Distribution assembly, equipped with switchgear and transformer to provide 230 volt, 110 volt and 24 volt supplies via an arrangement of socket-outlets, all as detailed below.

Enclosure
In standard configuration the enclosure is wall mounting and of sheet steel construction. The enclosure is finished by a system comprising of a zinc phosphate pre-treatment followed by a top coat of electro-statically applied, polyester powder paint, standard shade Dark Admiralty Grey. The wall mounting brackets are removable and can be repositioned to enable the enclosure to be floor mounted.

Incoming Terminals
Suitable to loop-in and out 2 x 6mm2 conductors. The terminals are shrouded to IP2X. The over current protection at source should not exceed 32A.

Incoming Switchgear
Fitted a 32 amp, DP switch disconnector to IEC 60947-3, fed from the incoming terminals. The switch does not control the loop-out feed.

Distribution 230V

1 no. 16A 30mA SP and switched neutral Type A RCBO feeding a twin 13A socket, metal clad.
1 no.  10A SP Type D MCB feeding a 2 kVA double-wound transformer to BS EN 61558, parts 1 and 4 but with an earthed secondary winding. The main transformer ratio is 230:110 and the primary winding is tapped at 220, 240 and 250 volts. The transformer incorporates a separate 24V SELV tertiary output winding.

Distribution 110 volt
The output of the secondary winding is 110 volts CTE, rated at 1750 VA and provides a Reduced Low Voltage (RLV) supply in accordance with BS 7671. The winding feeds 1 no. 16A DP Type C MCB feeding 2 no. 16A, 110V, 3P, BS EN 60309-2, IPX4 sockets.

Distribution 24 volt
The output of the tertiary winding is 24 volts earth free, rated at 250 VA and provides an SELV supply in accordance with BS 7671. The winding feeds 1 no. 10A DP Type C MCB feeding a 16A 2P, 24V, BS EN 60309-2, IPX4 socket.
