Why Older Ardmore Homes Require an Electrical Check First
A home built before 1940 in Ardmore was designed and wired for the household loads of that era. The electrical service to a pool pad that was run when the pool was added in the 1960s or 1970s was typically sized for a single-speed pump motor and perhaps a pool light. That was the full expected load at that time.Â
When a homeowner in 2026 wants to add a variable speed pump drawing its full range of power across different operating speeds, plus a salt chlorinator with its own control board and cell, the total load being asked of that original electrical service is meaningfully different from what it was designed for. In many cases the wire gauge running from the panel to the equipment pad and the breaker protecting that circuit were sized for the original equipment, not for what the homeowner wants to install today.
This is not a reason to avoid upgrading. It is a reason to check before ordering equipment. An electrical service assessment at the equipment pad takes less than an hour and tells us whether the existing configuration can support the new equipment, whether a circuit upgrade is needed before installation, and whether any of those changes require a permit from Lower Merion Township or Haverford Township depending on which section of Ardmore the pool is in.Â
Finding this out before the equipment arrives on the job is the difference between a clean installation and a situation where equipment sits on the pad waiting for electrical work that was not anticipated.
