A straightforward single-phase surge-protection installation starts from about R2,350 where the DB board has suitable space, the earthing arrangement is sound and an entry-level live-and-neutral protective device suits the installation. Surge protection is a coordinated system, not a decorative add-on: device type, upstream protection, conductor length and earthing all matter to performance.

Why prices move
Four factors that change the final quote
A better quote explains the variables instead of hiding them inside one number.
Supply configuration
Single-phase and three-phase installations require different devices and conductor arrangements.
Board capacity
A full or non-standard board may need an enclosure or layout upgrade before a device can be fitted safely.
Earthing
Surge energy needs an effective path; poor earthing can undermine the protection strategy.
Protection level
Whole-board, sub-board and sensitive-equipment layers have different scopes and budgets.

Questions people ask
Surge-protection installation FAQs
Will surge protection stop load shedding?+
No. It helps manage transient overvoltage; it does not provide backup electricity during an outage.
Does it protect every appliance?+
It reduces risk within its design limits. Sensitive equipment may justify additional point-of-use or coordinated protection.
Is the protective module included?+
An entry-level single-phase live-and-neutral device is included in the starting basis. Other configurations are quoted.
Can it fit in any DB board?+
No. Space, compatibility, conductor routing, earthing and upstream protection must be checked first.
Does the device last forever?+
No. Surge devices can degrade or operate during events. Their status indication should be checked and failed modules replaced.
