"Jonathan installed my Emporia Pro charger in my garage, and I couldn’t be happier with the experience! From the very beginning, he was quick to respond, offered a fair price, and made the entire process smooth and stress-free. He was punctual, professional, and kept me informed every step of the way. As someone who is new to EVs and home charging requirements, I had a lot of questions. Jonathan patiently answered every one of them and explained everything in terms that were easy to understand. His knowledge, attention to detail, and excellent customer service gave me complete confidence that the job was being done right. The installation turned out great, and I have absolutely no regrets choosing him for this project. I highly recommend Jonathan to anyone looking for EV charger installation or electrical work. I will definitely be calling him again for future projects!"

"Updating this Zinsco electrical panel has been our top priority. Our home inspector warned that the outdated brand has become obsolete and creates a great risk to homeowners due to their faulty circuit breakers. This meant that if our circuit was overloaded or short, the breaker wouldn’t trip, and we would be tackling an electrical fire. We are so grateful to Elias Sugui (@certified_electrical_services) for taking on this project with ease. His calm demeanor and obvious expertise settled our nerves. From inquiry to execution, Elias provided exceptional service and professionalism. We’ll be sleeping much better knowing the job was done by him. We highly recommend reaching out to them for any and all of your electrical needs!"

"Dick and Dave reviewed my plans to install a level 2 electric vehicle car charger in my garage, which included a full rewiring of the entire garage, and installation of a new 20 breaker 200 amp subpanel. Dick was very responsive and was helpful with researching the project design prior to pulling the city permit. Dick provided the written estimate at a reasonable price. They started work immediately once I approved the project. Dick and Dave were very prompt and professional with this installation. I will highly recommend Aloha Solar and Electrical to my friends and family. Mahalo Dick for all your help on my project."

Electrical questions, answered by experts

A piggyback circuit breaker, also known as a tandem or double-stuff breaker, combines two separate circuits into a single slot in a breaker panel. This design allows adding more circuits without a larger panel, making it a space-saving solution. Each breaker in the piggyback unit operates independently, protecting two circuits in one standard breaker slot. This is especially useful in older panels with limited space for additional breakers.

The number of outlets and lights you can safely run on a single circuit depends on the circuit's amperage and local electrical codes. A general rule is to allow one outlet or light fixture per 1.5 amps, keeping the total load under 80% of the circuit breaker's capacity. For example, a 15-amp circuit can typically support up to eight outlets or lights, while a 20-amp circuit can accommodate up to ten. Always consider the combined power usage of all connected devices and fixtures to prevent overloading. For specific guidelines and to ensure safety, it is best to consult local electrical codes or a licensed electrician.

It can be safe to buy or live in a house with knob and tube (K&T) wiring, but only if the system is in good condition, functional, and has been thoroughly inspected and approved by a licensed electrician. Never purchase a home with K&T wiring without getting a professional electrical inspection first.

Key considerations include:

  • Safety and Condition: An inspector will verify that the wiring is safe and has not deteriorated. Over time, the insulation can wear away, leaving exposed wires that pose a significant fire or shock hazard.

  • System Capacity: The electrical service should be at least 60 amps. However, even at this capacity, K&T systems often struggle to handle the demands of modern appliances and electronics.

  • Lack of Grounding: Knob and tube wiring is an ungrounded system, which is a safety concern for many modern devices.

  • Ongoing Maintenance: If you live in a home with K&T wiring, it's recommended to have it inspected by an electrician every one to two years to ensure it remains in safe working order.

Ultimately, any inspection or modification of a knob and tube system should always be performed by a certified professional.

GFCI outlets help prevent dangers from ground faults that can cause shocks. This is a different issue that a ground circuit can’t fully address. It’s best to use GFCI outlets combined with ground circuits for complete protection for you and your electronics.

To install an outlet from existing wiring, you’ll need to choose a location where you can already access existing wiring. The easiest way to do this is to install an outlet on the other side of the wall of an existing outlet. 

Since the wiring is already in place, all you have to do is connect a new cable to the existing wiring and then connect the correct wires through the wall—to the new electrical outlet. Place your new outlet into the opening in the wall and then connect the correct wires to the appropriate terminal screws.
