FAQs Electrical:

Here are some of the common questions, if you have any other questions please contact me by phone or email.

What is an RCD and why do I care?

An RCD or residual-current device is a leak detector and is for human safety.

It measures the amount of power going into and coming back from a circuit. if only a very small amount out, the RCD trips and saves the humans and property from further harm and risk.

A fuse or circuit breaker is a safety device that activates over the circuit load. This is much more than a small leak of electricity that would activate an RCD.

How much is it to wire a house?

Depends on various factors: Mains from street; how many light and power outlets in each room; the size of the home; additional services such as home automation, security, TV, data, & phone. I am happy to quote off plans and/or talk about the project needs with you.

Why can’t I just pop an extra light or power point in?

Since first established in 1927 in New Zealand, electrical regulations have been constantly changing with an emphasis on better electrical protection and safer electrical practices. The aim is to reduce the amount of fatalities, injury, and fire caused by electrical works.

When an Electrician changes a circuit, that circuit needs to comply with the regulations of the day. If your electrics are old, chances are they would not completely comply with today’s regulations. I can often give an indication over the phone or by email, if given the age of the building, existing alterations of significance, and desired electrical additions.

I have some dodgy power points and lights. How much is this work likely to be?

Electricians are allowed to change old existing fittings for new like fittings as long as faults are not found in the related wiring. These maintenance repairs can comply with the electrical regulations of the year the wiring was originally completed. So costs can potentially be limited to the fittings, labour for changing the fittings, and an electrical warrant of fitness.

In the 1960’s and older buildings, the original wiring may not be safe to work on. This old wiring used cloth or rubber insulation. In many cases, this insulation cannot bend without some breaking off and exposing the live wires inside. This is often when rewires are recommended to change the building’s wiring completely for new electrical wiring.

As a rule of thumb, “the older the building, the worse the wiring”
Wilford Services can give an indication over the phone or by email. It may be worthwhile to invest in a comprehensive electrical report to cover existing electrical systems and suggested solutions.
