I’ve been in the electrical trade since 2017 and I journeyed out in 2021. I do a lot of commercial/residential work, traffic signals and sports lighting. I don’t mind traveling to work.i can trouble shoot, install lights, breakers, ceiling fans, ev chargers, panel upgrades, and pretty much any thing electrical I can do. im dependable, hard working, pay close attention to detail and making sure the customer is always happy. I’m looking for extra work because I enjoy this trade and want to give people a product they want with out spending a arm and a leg.

Hi my name is Don. I’m 43 years old.\nI have been in the trades for 23 years.\nWhen I was 19, I worked for a contractor who remodel custom luxury homes.\nI spent five years with them and then took what I’ve learned and started a small any man business in California. \nShortly after that economy started to slow down, so I focused on one trade.\nNow that things are looking better I’d like to get back to what I did before.\nI have experience in everything from concrete to roofing, and everything in between.

"Very good job, because of the job we had to help but kinda knew that was a possibility I was aware of. Great to work with and got a very fair deal partially because we were willing lend a hand. Have a woodworking business and I was installing some new breakers and outlets in my shop. So he did need a little help running some wire, long stretch about 80ft and conduit was already installed and had a couple 90 degree corners tough job for any one guy."

Generator Install questions, answered by experts

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
