What are the benefits of RCDs for Castle Hill residents? 

A Residual-Current Device (RCD) is a safety switch designed to monitor the electrical current through a circuit and cut off the supply of electricity automatically in case of a detected fault. Once installed, RCDs offer additional protection to electrical shocks that ordinary fuse and circuit breakers cannot. 

Do your Castle Hill electricians provide Certificates of Compliance? 

A Certificate of Compliance demonstrates that all electrical work has been completed to the required industry safety standards. The Certificate of Compliance must be issued to the customer, Fair Trading NSW and the electricity supplier within 7 days of completing the electrical installation or testing. At O’Brien Electrical, all our licensed and certified electricians provide certificates of compliance after completing work.

"O'Brien Electrical Castle Hill have been installing Hotwire Under Floor Heating on our behalf for some years. Their service and support is outstanding. Highly recommend them no matter your electrical requirements."

Luke Chant

"As one of the owners of Cassin and Sons Construction, it has been my pleasure to have O'Brien Electrical Castle Hill contract on many of our projects. Adrian and team have been on time and on budget on all their projects As a Building and Cabinet making Contractor, it is great to have O'Brien Electrical Castle Hill on the job as the electrician. There is rarely a problem and when one arises, there is a solution; not a sense of 'it's not my problem. The crew have been on time, every time, and often lent a hand to other subs to get the project done. It is refreshing to see someone committed to completing the project as a whole rather than the attitude that my work is done, call me when you are ready for the next phase. I have great confidence in O'Brien Electrical Castle Hill, and I will continue to rely on them for all of my electrical needs; big and small. I would highly recommend O'Brien Electrical Castle Hill for any and all electrical projects."

Cassin & Sons

I recently called them and had Scott complete two jobs in our home. I found Scott very polite, organised and professional. Even though it was a hot day, he worked around the house really quietly, while my 2-year-old was asleep! He seemed to respect being in someone else's home. The whole experience felt very professional, from the team who answered the phone and quoted the job, to the young apprentice who accompanied Scott. I have since called them for a second time and happy to recommend"
