You need a new main electrical panel. You then have one or more subpanels in the house. The electrician needs to connect another feed into the main electrical panel or one of the subpanels to feed your pool equipment. Wherever that feed to the pool equipment is connected to needs space for a circuit breaker, which your existing box does not have.
Fair price. It's a meter pan and main disconnect. The new one will look much nicer and cleaner that's old school
Thank you all for the response! We did the work today. $1kPlease post finished product of the new electrical install.....
