1- How do safety switches save lives?

On an electrical circuit circuit, the current flowing to an appliance/light returns through the neutral wire. If the circuit is damaged, the electricity can leak to earth through a person in contact with the appliance/light fitting, causing death or serious injury. A safety switch detects the loss of power from the circuit, and cuts the supply of electricity in as little as 30 milliseconds – 0.003 seconds. Importantly, this response time is faster than the critical section of a heartbeat, and therefore significantly reduces the risk of death or serious injury.

 

2- Do my safety switches need testing?

Yes, they most certainly do. It is highly recommended to push the test button on the safety switch at least every 6 months to ensure correct operation. If you are unsure about this procedure, please call us. Also, if the safety switch does not trip once the test button is pressed, this means the unit should be replaced by an licensed electrician ASAP

 

3- What can I do to save on electricity costs?

One of the best and easiest ways to save on electricity costs is to replace all halogen lamps over to LED. Halogen lamps can use up to 9x the energy as an equivalent LED globe/downlight. Not only are LED lights energy efficient, they also run at much cooler temperatures which goes along way to protecting your home and family from fire.

 

4- Why do my LED lights flicker. Mostly at night?

This is caused by the ripple frequency injected through the transmission lines to control off-peak tariffs. Even if you don’t have an off-peak tariff personally, it is just a general signal sent across the network so every house receives it. The flickering lights can be easily fixed by installing a ripple frequency filter.

 

5- Can I install the cables myself and have you back to complete it?

NO! You definitely cannot do any DIY installations as its against the law and potentially lead to an extremely dangerous situation. Your house insurance will also be voided if there was to be an electrical fire. Please do not put your family at risk by doing DIY electrical work, call a fully licensed and insured electrical contractor.
