There are many responsibilities that you face as a business owner, and one important responsibility is ensuring the proper function of your building’s electrical system. The following are a few of the things that your commercial electrician in San Jose would want you to know about electrical maintenance for your property : 
Periodic safety inspections are essential.
No matter the age of your building or your type of business, scheduling an electrical safety inspection now and then is a must. Also, having a commercial electrician take a look at the electrical wiring before you move into a new building can help ensure that there are no problems with things like the electrical panels and underground wiring. Regularly having an electrician ensure that your building’s wiring is in good shape can help reduce hazards and protect your electrical system from damage and the need for costly repairs.
Some buildings need new wiring.
To help protect the safety of your team, as well as prevent damage to your property, it’s important to know whether your business needs rewiring. Having an insufficient number of outlets, an obsolete or malfunctioning circuit breaker, or the presence of old, ungrounded, cloth-insulated, or aluminum-containing wiring are all indications that your building could benefit from rewiring services. Having your building rewired can help ensure the ongoing safety of your employees and better electrical service capacity for your business.
Breaker and fuse replacements should be left to professionals.
It’s not uncommon for someone who has worked on a residential breaker box to assume that updating or repairing a commercial one requires the same levels of electrical knowledge, skills, and experience. However, the breaker boxes installed in commercial buildings tend to be more complicated than those used in residences. For this reason, it’s important to contact a commercial electrician about things like breaker and fuse replacement, rather than try to tackle the job yourself. Also, calling an electrician for this task will give him a chance to evaluate your breaker box and determine if it should be replaced with a newer and safer model.
