## Electrical Installation Code Singapore 

- Brief history:
-     SS CP 5
- started in 1977 and based on UK’s Institution of Electrical Engineer (IEE) Wiring Regulations
- revised in 1988 and then 1998
- latest revision in 1998 was based on IEE Wiring Regulations 16th Edition (or BS 7671:1992 Requirements for Electrical Installations)
- drawn up to ensure safety, especially from electric shock and fire in the use of electricity and related principally to the design, selection, erection, inspection and testing of electrical installations

- Electrical Safety Systems for the Asia-Pacific

## Electrical Installation Code Singapore 

- some of the clauses in the IEE Wiring Regulations were amended to suit local conditions, indicated by the letter “L”  immediately after the clause number
- Examples of significant changes are:
- type of system earthing for electrical installations shall be TN-S system or TT system
- use of residual current circuit breaker having a rated residual operating current not exceeding  30 mA and an operating time not exceeding 40 ms at a residual current of 150 mA for socket outlet and lighting circuits in domestic premises

- Electrical Safety Systems for the Asia-Pacific

## Electrical Installation Code Singapore 

- switch for every 13A socket outlet
- where products are available under the Singapore Standard, the Singapore Standard No is used instead of the BS or IEC No;

## Electrical Installation Code Singapore 

-  -  SS CP 88 Part 1
- Formerly known as CP 44
- latest revision in 2001
- drawn up to protect persons and property against electrical hazards - supplement the general requirements of SS CP 5 in the use of temporary electrical installations in construction sites
- give guidance on good practice for the inspection, testing and maintenance of temporary electrical installations operating at voltages up to 1000 volts ac which are widely used in construction and building sites

- Electrical Safety Systems for the Asia-Pacific

## Electrical Installation Code Singapore 

-  Examples of significant changes in the lastest revisions are:
- Use of TN-S system only for any temporary electrical installation taking supply from generating set(s)
- installation and earthing requirements of generating sets
- all circuits shall be protected by residual current devices
- all final circuits shall be protected by residual current circuit breakers or residual current devices
- adequate mechanical protection for cables and wiring installed at site

- Electrical Safety Systems for the Asia-Pacific

## Electrical Installation Code Singapore 

- guidelines on the use of socket-outlet assembly (SOA) for the connection of portable equipment at locations where fixed socket-outlets may not be available
- guidelines on the use of extension cable for portable equipment
- prohibition on the use of cable armour or metallic cable shealth as protective conductor
- monthly inspection of temporary electrical installation by the competent person engaged by owner

## Is the code used by construction contractors on a local, regional or national basis?
Both SS CP 5 and SS CP 88 Pt 1 are used by construction contractors on a national basis
Possible alternative codes that are allowable
compliance of SS CP 5 and SS CP 88 Pt 1 are  mandatory requirements, they are aligned with BS 7671:1992 Requirements for Electrical Installations

## Types of installations that require the use of the code
SS CP 5 is applicable to all consumers’ electrical installations in industrial, commercial and domestic premises
SS CP 88 Pt 1 is applicable to temporary electrical installations in construction and building sites 
The codes do not apply to electrical installations in electrical power stations, transmission or distribution plants, etc.

## How often is the Code updated?
As and when the need arises.  
Is the time period fixed or variable?
Review every 5 years. 
Impact of external/international activities, organizations?
Revision of code is to address the concerns and needs of the industries, wherever necessary, localised conditions will be included to ensure feasibility for compliance.  Sufficient grace period will be given for compliance by the relevant industries.

## Evidence of compliance -- certificate issued?  
For electrical installation designed to take electricity supply from the the public electricity supply system, the competent person is required to certify fitness of the consumer’s electrical installation.  The electricity supplier will conduct site inspection and if the installation is satisfactory, a “statement of turn-on” will be issued by the public electricity supplier and followed by turn-on of electricity supply.

## What is the dispute settlement process?
The competent person (licensed electrical worker, LEW) is responsible for his certification for the purpose of connection of electricity supply.  Both the public electricity supplier and the public transmission licensee have the authority to refuse connection of electricity supply if they found the consumers’ electrical installation is unfit for connection to the public electricity supply system.  The LEW has to make good the defects to the satisfaction of the public electricity licensees before connection of electricity is permitted.

## 
What are the penalties of non-compliance?
For electrical installations do not comply with the relevant code of practice or technical requirements of the public transmission licensee, the penalty to the consumers concerned would be refusal for connection of electricity supply to the consumer’s installations by the public electricity licensees.  Appropriate disciplinary action will be taken by EMA if the LEW is found omission or negligence in his work.
