MT Series Powertrack Technical Info

The 63 Amp MT Powertrack System caters for single phase standard, UPS and low noise (CE). The 50 Amp System caters for three phase or dual applications where both standard and low noise (CE) power are run together within the same track system using reduced floor area and installation time.

Powertrack comes in lengths of 1.2m, 1.8m (only available in 300mm pitch) 2.4m or 3.6m with tap-off positions provided at 150mm, 300mm or 600mm. The system is therefore very versatile and suitable for high through to low density tap-off requirements – so access to power need never be a problem.

Both snap-fit couplers and tap-offs are key and colour coded to avoid any possible errors during assembly. For maximum safety each operates a shutter on insertion to ensure no accidental contact can be made.

KEYS

INSTALLATION

MT Powertrack used within raised access floors is normally arranged in parallel runs with the feed units to the Powertrack orientated towards the incoming supply. This offers an economic format inherent in long straight runs. Spacing should be a maximum of 5.5 metres between each length of track and 2.5 metres from the perimeter when using a standard 3 metre tap-off to a floorbox thus offering optimum layout flexibility.

Attention should be given to the total power requirements to avoid exceeding the maximum power rating of the track. This is based on the maximum power requirement for each floor outlet box.

Powertrack Installation

Starting with the Feed Unit, remove the dust cover over the key and colour coded socket and simply snap the integral coupler, pre-installed on the Powertrack, into the feed socket. The next length of track is then fitted to the socket end of the first length of Powertrack as previously described, this is then repeated for the following lengths until the run is complete. On the final length of Powertrack section the adhesive dust cover over the socket is maintained. This offers additional protection for the shuttered socket from dust or dirt. The Feed Unit is then secured via the slots in the base and the Powertrack every 1200mm (max) by using the mounting brackets provided.

Tap-off

Provision of power is provided along its length by inserting a colour key coded Tap-off unit into a shuttered socket. Each Tap-off position on the Powertrack is protected by a shutter and adhesive dust cover to further protect the outlet. The tap-off unit comes complete with LSF cabling welded directly to the contacts with a flexible outer steel conduit. Removal of the tap-off can only be achieved by releasing the twin integral clips which operates automatically on plug insertion which may be performed whilst the whole system is live.

NB There are numerous Tap-off configurations available. Please contact 0870 121 9990, for your exact requirements.

Technical Specifications

Third party certified and tested to comply with:

BS EN 60 439-1: 1999 IEC 60439-1: 1999

BS 5733: 1995 where applicable

Marshall-Tufflex is registered by BSI to BS EN ISO9001 MT Powertrack is designed to comply with the requirements of BS 7671: 2001 (IEE Wiring Regulations).

Earth Fault Loop Impedance

BS 7671: 2001 (IEE Wiring Regulations) requires the total earth loop impedance, to be sufficiently low to operate the protective device within the specified time, namely is 0.4 seconds, to circuits supplying socket outlets which may supply handheld equipment.

Section 607 Installations BS 7671:2001 Earthing Requirements for the Installation of Equipment having High Protective/Conductor Currents.

 The scope of Reg. 607-02-04 requires that every final circuit intended to supply one or more items of equipment, where the total protective conductor current is likely to exceed 10mA. in normal use, shall have a high protective connection. All MT Powertrack 507 tap-off units conform to the high integrity protective requirement by virtue of using a protective conductor of 4mm2 enclosed within a flexible conduit, thus providing additional protection against mechanical damage. Regulation 607-02-04(ii).

32 Amp 3 metre tap-off unit

The 32 amp tap-off unit comprises of an unfused tap-off a flexible metal conduit with integral 4mm2 LSF conductors. These units are designed to comply with regulation 473-02-02 of BS 7671 by virtue of the following:

1. Maximum length of cable is 3 metres.

2. Minimum risk of fault current as the item is factory assembled and fully tested.

3. Fully protected by flexible steel conduit located within raised access floor which offers further protection.

5 metre tap-off unit

Tap-off units in excess of 3 metres should only be used if they contain a fuse or the powertrack is protected by a 32 amp rated protective device.

DIMENSIONAL DATA

MT SERIES 507 IN-SCREED TECHNICAL INFORMATION

MT Series 507 is a three compartment floor distribution system designed to be installed in a 60mm-65mm depth of screed. Both the service outlet and junction box are both fully internally segregated to suit either the PVC-U or steel duct section option. INSTALLATION See instructions supplied in box. Planning the layout is essential as alterations are impossible once screed is laid. Service and junction boxes should be placed in position making sure that the top of the boxes are level and in line with expected finished floor level. Depending on actual screed depth, this can be achieved by using the screws provided to the base of the box. Once satisfied boxes are in correct position, PVC-U or steel duct can be used to link between boxes. Alternatively conduit can be used by utilizing the 20mm knock-out in the blank plate. Note: Service box can only be used as a through box, whereas the junction box has all round access, with internal segregation. Once the screed is in situ the support trim can be adjusted to the finished screed level. The accessories are terminated and the trim and lid fitted. ACCESSORIES Duct adaptors and blank ends are available for both junction and service boxes and should be ordered separately as per individual requirements. These are not supplied with the boxes. For additional lengths of ducting, a connector is available. Flat bends and vertical bends are used where a single change of direction is required. MOUNTING PLATES All plates use a standard 185mm x 95mm format encompassing plates for use with standard 60.3mm and 120.6mm accessories with blank or prepunched plates for data/tel etc. Any configuration is possible using these plates.
