Wiring rolling shutters

[accessdoors]

As a supplier of 240 volt electric rolling shutters to shops etc, many suppliers simply fit a plug to the end of the motor and plug it straight into a socket. Is this OK

a)For an unqualified person

b)comply with regulations.

there is no way for an unqualified man to check the quality of such sockets.

Provided the load is within the capacity of a 13 amp socket then probably ok but this maybe classed as fixed equipment in which case a fused spur is probably better. A simple plug in tester can be used to check polarity and for an earth presence. Earth bonding may be essential. If I were you I would engage an electrician to carry out the electrical side and charge (with a markup) to the customer as part of your installation.

Further thought, if the shutters are accessable to the public outside then an RCD is also essential. Install properly to avoid problems.

Nearly correct Stanleyman if a plug top is fitted then it would be classed as portable equipment so it would have to be P.A.Tested but because it is a fixed appliance then a switched or unswitched spur unit will need to be fitted within the property and the door doesn't need an RCD device cause it's a fixed appliance not connected to any kind of water and as for bonding there is no regulation that states you need to earth it other than the motor being earthed.

[stanleyman]

If the shutters are accessable from outside then it will be classed as an external supply and needs an RCD, an earth fault could liven it to anyone outside. It doesn't need to be connected to water to need earth bonding, any metal work should be, this is not domestic. This motor unit maybe double insulated from the door which may change things but I agree it should be wired as fix equipment (which doesn't normally require an RCD if not accessable from outside). Plus additional precautions as necessary.
