Switchboards & Safety Switches

Certified Switchboard installation experts

73 Electrical are your experts in certified switchboard installation. We service the Gold Coast and Brisbane’s southside.

Our fully licensed electricians can provide professional and safe switchboard upgrades, repairs and installations. And we do the same for safety switches, keeping your home or business safe.

Switchboards direct electricity from the power supply to smaller regions of usage (controlled through safety switches). It is a very crucial unit of any home. Switchboards contain circuit breakers, and they must be incorporated with safety switches under Queensland law. Safety switches will isolate the circuit immediately when an electrical fault occurs.

Thank you for my switchboard upgrade, it was achieved with no fuss and no mess. Dennis supplied the knowledge and materials to back my queries regarding protection for my computers. Highly recommended.

Dennis is an excellent service provider. He arrived on time to an urgent job that I had as a tenant and carried out all the jobs quickly and efficiently and left very little for me to clean up. Will definitely recommend 73 Electrical to others.

Karen Broder

We were very happy that we chose 73 Electrical for our electrical project. From the first phone call to Dennis we received a friendly and courteous response. The work was very professional and Dennis was very dependable. It was a pleasure doing business with 73 Electrical and we will be sure to call in the future for all our electrical needs.

73 Electrical were prompt, professional and friendly. Our power went out and we called Dennis immediately, he understood the urgency to get our power up and running. What a service!.


I cannot recommend Dennis enough!! We had all our internal lights replaced by Dennis, half of which are on dimmers. He was fast, efficient, and beat all other quotes we received by a landslide!!! Dennis even got us a tradie discount at the local electrical wholesalers. The work was neat and tidy with high quality workmanship. Thanks Dennis!! You will be our preferred electrician for all future work.

Over the last three years Dennis from 73 Electrical has been my electrician. I have to say he does an excellent job and goes above and beyond on all my jobs sites. He has done little jobs to 350m^2 new build projects for me and does a great job every time.
